Dolibarr 7.0.1 | Module Projects | Module Agenda

as in version 7.0, the following error still exists in version 7.0.1:

In the Projects module, the time information for the project can not be changed later.
I once hung a screenshot (1). In an attempt to change the date, the question mark remains in the field.

Even in the Agenda module, the date for the project or a manually created appointment can not be changed.
There is also an error message (field date required), even though it was previously entered. To be seen in the screenshot (2). When trying to create an appointment manually. In addition, the appointment is not saved.

Same server with version 6.0x is running error free.

Solved in v8.x
