Spreadsheet - Strange Content

[Dirk.]

Thank you,
writing a number to E5 and typing E1:ZZ5:={{}} shows that it in principle deletes something (the content of E5) but E1:ZZ5 still contain the strange content.
So maybe this is the third bug in three day I found in the spreadsheet. Quite Disappointing.

Greetings
Dirk.

Edit: Hitting delete of course does no delete the crap in the cell... It only brings it back after something else was in the cell. And I will for sure not clear the spreadsheet to lose my content.
Edit2: Same result for E1:ZZ5:={} ... deleting content, but not crap.
