line break disappeared in last update

I updated both numbers and the OS so I am not sure which update caused this issue :

Numbers last update version 14.2 (7041.0.109),

Mac OS sequoia 15.0

In a table, I used line break (simple return) all the time within a cell by either pressing return, command+return or control+return (I can't recall which one of these as it was natural and I did it without thinking)

It did this :

with the hotkey highlighted :

Now after the update this hotkey is gone, and I couldn't find a new similar one.

The only line break option I have left is option+return which is different as it adds an extra spacing :

The numbers hotkey chart in the help section give these 2 entries that both are not working ... (they both just select the next cell, no formatting whatsoever) :

Insert a line break (soft return) Shift-Return

Insert a paragraph break Return

Looks like a bug, or maybe there is some secret other new hotkey I should know of ?

thanks for your help
