Why cannot I finish the weekly repeater ahead of time?

test1 and test2 are two tasks. test2 is repeated every day and test1 is repeated every week, I can complete the task test2 ahead of time (click todo now, and the date becomes 22.12.19).
However, test1 cannot be completed ahead of schedule. I click todo and nothing happens. Why?

the repeater gets generated with one + too many when using a week.

seems like atm you have to correct that manually.
