Mojave 10.14.6, LO 18.104.22.168
In the attached document, when I close and open it, the Row Height of some rows shortens to obscure the text in columns L - AP, rather than staying at the appropriate height at which it was set.
I then reset the heights to be the correct height again using Optimal Height each time I open and close the document.
Normally this wouldn’t be such a big issue, but due to the nature of how this document is used (it is closed an opened fairly often) it’s rather inconvenient to have to set rows to Optimal Height every time it happens.
Plus I’m just wondering why it’s happening at all.
It does use Conditional Formatting based on another (sensitive, therefore I haven’t included here unless I need to) document, however I fail to see why this should be an issue.
