Problem with TwwCalendarEdit

Hello,

we have a problem with the TwwCalendarEdit. When we test the component and set a time, on the 3rd time setting the date also reacts and adds a day to it.
But only in iOS and ANDROID! In VCL (Windows) it works fine!
We bound the component through a TBindSourceDB with a DateTime-Field in a TFDQuery.

Delphi 10.4.2
Properties:
CalendarAttributes.ShowMode := wwpsmDateTime
DataType := wwDTEdtDateTime
DisplayFormat := dd.mm.yyyy, hh:mm

Thanks in advance!

Stefan
