Yeah i should probably disable the issues on github, i dont expect anyone to post there

I reproduced the issue, thanks for reporting! The values are being applied/edited correctly but the display is wrong, it currently only extracts the first number of whatever you set (except nothing is set, then it shows 15 days which is default). E.g. set to 100 and it would display 1 but in reality it would collect 100d.
You can check back in task manager details tab, you need to add the column "command line", there you see what the textbox should display:
