It is now September 2024 and I am using FreeOffice 2024 for MacOS (latest version). Unfortunately this problem is still around and it is very annoying. I have tried No 5 i.e. renaming the document and this cures the problem for a while but then it surfaces again. I faced this problem in both Text and PlanMaker. I am running SONOMA 14.6.1 in an Apple MacBook Pro (16-inch, 2019).
Processor: 2,6 GHz 6-Core Intel Core i7
Graphics: Intel UHD Graphics 630 1536 MB
Memory: 16 GB 2667 MHz DDR4
Come on Softmaker... about time to solve this problem! Please...
PS
I also checked 1 to 4 but to no avail.
