Please, could you put your question in ask.libreoffice.org
Cant reproduce in 7.5.5.2 on Linux, but the limited information you gave makes it difficult to know if I'm testing the right thing. Please see https://wiki.documentfoundation.org/QA/BugReport for info on reporting bugs. A good report will include version information and detailed steps to reproduce the issue. For now, closing as "invalid" given we can't even tell if it's a question or a bug.
