Running out of fresh RC passeges

I've been subscribed to 7Sage for at least six months. I'm starting to run out of actually new reading comprehension passages, and I was wondering if anybody else has been running into this issue? When I select fresh on a drill, it says I don't have enough passages to fulfil this requirement. I'm confused about how this can be because I find it hard to believe that I have done all of the available Reading Comprehension passages, especially since I know that I still have more practice tests on LawHub that I have not yet taken, and I'm also not running out of LR despite training sections of that just as frequently.
