掲示板 Forums - Vocab rescheduled after learning new kanji

It seems to me that disable option for reset mastery of associated vocab when learning kanji doesn't affect anything. My steps:

1. Learn all scheduled vocab and kanji with option to first learn them than new;
2. Learn new kanji and complete the quiz;
3. Notice that on vocab's schedule appeared some words to review;
4. When I clicked on that number it show that associated vocab for that learned kanji reappered on scheldure.
   

It happend several times for different days and do not depend on the option what to learn first.
