Issue mostly described in the summary.
If I try to clear values for Start date and End date (Start date field used by SoftwarePlant plugins). When I clear the value on Edit-Screen it disappears from the view. If I go to 'Edit' page I see that the fields are again filled automatically with the same date as for End date.
It seems that it is not clearing in Database instead of it fetches data fro database and refill.
Described with Screenshots:
Inital phase
Date deleted (disappeared as expceted)
By click on "Edit"
I tried than to delete both. After saving it was refilled with some random dates from the past like Start date: 13.01.2020 End date: 06.06.2020
Can someone help please
