Auto time entry acceptance don't work

In the settings, I enabled the “Automatically approve all AI time entry suggestions” feature and set the “Automatic tag acceptance” parameter to 40%, but I still have a lot of pending time entries. On full workdays, there are as many as 30. Can this feature be fixed? It’s impossible to review that many time entries. I’m fine with the AI approving them all automatically; I can correct them manually if necessary.
