Doing a SAVE Doesn't Save Formatting Changes ?
 

Hello,

Using Ecel on a iMac. Purchased as part of MS OFFICE.
Version is 15.41

Everything seems to work fine, but when I do a Save from the top bar
pull down menu,
the formatting changes I may have made do not come back when re-opened again.

Shouldn't a normal Save actually save these changes ?
Is this a "known" problem ?

What might I, as usual, be doing wrong ?

Thanks,
Bob
