Difficulty with entering correct dates in popup calendar, a must in genealogy when working with others or finding a relation with familys. Error in di

Hello,
Just installed the programm on our site and fill in the first FamilyTree. Error 1: If I check the “living” or not and I choose not living, and enter the date oif death, the window says after opening “person is living”
Error 2: if I donot know the exact date of death, so I have only the year and no month or day I can not close the popup window;
and can not alter the date in the presentation-line. It is incorrect. Is it ours or yours configuration?
Opening the FamilyTree from yesterday the data are not correctly saved
Best regards Peter Lex
