This is a dedicated tracker to investigate and fix missing question statistics on the question bank page.

After releasing MDL-75576 some sites still have no data in 'Needs checking?', 'Facility index' and 'Discriminative efficiency' columns, see screenshot below:

This is despite the fact that if I run the '\quiz_statistics\task\recalculate' task and checked its log, regarding the course I tested it prints the following: 'Quiz name' (149545) in course Course name (70244) has most recent attempt finished at 6/10/22, 15:49:40 and statistics from 15/02/23, 11:13:33 so nothing to do..
