Description:
Hello

I've found some strange bug. I've created long time ago file in which I fill some cells are create a "documentation list". It's very simple - just some merged cells with borders. Till version 5.4.4 everything was fine, but since 6.0.0 some borders are missing.

I have to return to older version.

I attach source file with two PDFs (01_6.0 - print from 6.0 version // 02_5.4.4 - the same file printed in 5.4.4 version). In all the files I had to delete or hide some data that I can't make public.

best regards
Mateusz
