Description:
I'm using LO 24.2.3.2 on Mac (Ventura 13.6.6)
The description of Calc/LO 6.2 states that when you move cells while holding down the Option key, the content at the insertion location shifts downward, doesn't get overwritten, and the content from the original location is transferred, not copied.

Expected:
a) The contents of the source cells or rows are moved and deleted at the source location.
b) The content of the placement location is moved down.

Result:
b) existing content at the insertion location is moved down, not overwritten. OK
a) the content at the original location is not deleted, the content then exists twice.

I have tried all keys and combinations when releasing, the content is ALWAYS copied.



Another bug in that instance: 
When moving entire lines, when I let go, they end up two lines ABOVE where I let go.
I.e. if I grab lines 14-16 and release (Option pressed) on top of line 8, they end up ABOVE line 6.

Steps to Reproduce:
1.Drag cell or line
2.release in desired place, pressing option key

Actual Results:
1. cell or line is moved to new place
2. "landing" cells are moved downwards
3. content of origin cells is still in place

Expected Results:
1. cell or line is moved, NOT COPIED
2. "landing" cells are moved downwards
3. origin cells are empty


Reproducible: Always


User Profile Reset: No

Additional Info:
The functionality should be restored, as described in Help

(sorry, found that one in German, not its English counterpart)

Second bug:
Lines push down the line where they are released - in the case I mentioned lines 14-16, pushing down the content of line 8, not line 6.
