I found myself in a similar situation with 5.0.3 both on Debian 8 and Win 7. I contemplated the idea to pay the developer to fix the bug(s) that were messing with my work.
Then, I realized that I could buy MS Word/Excel/Powerpoint for a fraction. And without waisting more than 5 minutes, no mail-judo required.
They eventually fixed that later, but for the time I had already switched completely to Office and use Debian for other tasks (a pity, since it is much more comfortable than Win 10).
