Cannot edit a already created task to repeat every last day of month

(works only for currently created tasks)

As you can see, when last day of month is used, I can only select every last thursday/friday etc of the month or the specific day, but not the last day of month.

I found a feature request https://product.akiflow.com/features-and-improvements-request/p/repeat-a-task-on-the-firstlast-day-of-the-month so I tried creating a new task and there I can see the option.

If I didn't check, I would have thought I can't have such repetition. Maybe the UI should be able to pick up and offer it also for edited tasks.
