Reset Vocab doesn’t work

Hi everyone. I tried to reset all vocab because together with grammar I racked up too many reviews. I reset both to start from scratch but it doesn’t seem to work with the vocab part. I also can’t find a way to remove them one by one, because when I enter a specific word in the review it only gives me the option to add it (while being part of the review already) and not to remove it.

Or is reset not the same as setting my reviews back to zero (which is what I want)?
