Did you want to state that none of the answers already given did work for you? If so, upvoting anything wouldn’t be ueseful or resonable at all.
If you suspect it’s a bug of LibO, you need to go to bugs@libreoffice.org and find out if the bug is already reported. If so you can comment on it there, if not you can create a report.
(This thread was visited thousands of times in more than 4 !/2 years and nobody linked to a bug. The many “metoo” contributions won’t help anybody. This is not a bug tracking site)
