Why all the brackets?

In my text document I have chapters with titles. Each title is linked via bookmark and hyperlink to the table of contents. I can understand that the bracket might show up because of either the hyperlink or the bookmark, but it seems like every time I open this document, more brackets are added.

Why are there so many? How do I get rid of them?

To get any sensible answer, re-open your question (press , then the “pencil” tool) to add OS name, LO version and save format. For best analysis, attach a sample file (with the problem still present).

Can you explain the process you used to set up your chapter titles and table of contents. It seems like you have gone to a lot of unnecessary work that resulted in the issue you describe.
