I use 3 of 4 vectors for learning cards. so say it says 200 to review, and I do review batch of 30, with no errors. cards after will go down to around 190. I think instead the review number should say the total number of reviews not just terms like in parens after. so in this case with 3 vectors, will show 200 (600) to give a more realistic estimate of how many more to do.
Are you using the "study multiple vectors per term" setting, where a term can come up multiple times in one day?
If *not*, then I would guess that you have (in your schedule's settings) turned on so that non-schedule materials are being mixed in. If that's the case, then the number is accurate - it's the number of reviews for that schedule that need to be done.
Yeah, it's the multiple vectors, then. Unfortunately, that is not a quick fix that I can drop in easily, but I can get to it at some point. It is accurate, just not useful (it does show the number of terms, but you want number of questions).
