I'll preface this by saying: This test is weird.
Adaptive tests don't work the way we're use to tests working, so that can make it hard to read the data. The difficulty levels that you receive will depend upon how you're doing in the rest of the section—so one possibility is that you're rocking RC so then you get really hard SC...so then of course you miss some of the SC.
The other variable here is that RC questions don't come one at a time; they have to come in clumps with the associated passage. So even when you're doing super well, you are still sometimes going to have lower-level RC questions (lower than your current scoring level), simply because the test is limited to choosing questions from that passage.
The data you cited shows that you're getting almost everything right on RC regardless of the difficulty level. So RC is great. For SC and CR, yes your percentage correct is lower—but you only saw super hard questions, so of course you should have gotten more of those wrong.
Can I ask what your actual score was? I'm going to guess in the lower 40s? That's in the 90th+ percentile, so your score is already really good. You should know that, although the scoring scale technically goes up to 51, it's rare to score higher than 45 on verbal. Even our own teachers don't often score above 47-48. So I tell my students that the practical upper limit on V is 45. (Oh, and another quirk: There's no V score of 43 for some reason. It literally goes 41, 42, 44, 45.)
I mention all of that because, if you're at like 42 right now and you're thinking, "I need to get this up to 50!" you really don't. If you're at 42, I'd say you have a range of 3 more points (up to 45). Let's say that your quant is at 45—there, the range goes up to the full 51, so you have 6 more points you could gain there. So you'd just want to balance that as you try to figure out what you can improve to lift your score further.
If your quant is at, like, 40—then I'd say that's your main priority now. If your quant is more comparable to the verbal in terms of the number of points you still have "to go" (up to 51 on Q, up to 45 on V), then yes, you'd want to try to address both.
For Verbal, once you get into the 40s, the potential opportunity is typically not for an overall question type but really for specific things that you see you're missing on any particular problems. Go back and look at the ones you missed. How often was it a careless mistake? How often do you look at it and think, Yes, I legit got that wrong, but I totally get why that other answer is better? How often is it—nope, I just didn't / don't know that and I still don't really get why that's the right answer? And finally how often do you think....I would like to argue with whoever wrote this because I still think I'm right?
Also for verbal at this level, a common issue is to be able to narrow it down to 2 but then struggle between the most tempting wrong answer and the right one. Do this in order to improve that last step:
(1) Why was the wrong answer so tempting? Why did it look like it might be right? (be as explicit as possible; also, now you know this is not a good reason to pick an answer)
(2) Why was it actually wrong? What specific words indicate that it is wrong and how did I overlook those clues the first time?
(3) Why did the right answer seem wrong? What made it so tempting to cross off the right answer? Why were those things actually okay; what was my error in thinking that they were wrong? (also, now you know that this is not a good reason to eliminate an answer)
(4) Why was it actually right?
