Attempting export to EPUB Results in the following error dialogue:
Error saving the document DocumentName:
The operation was started under an invalid parameter.
All associated files are in the same directory. Each of the linked section documents that are inserted into the master document export as individual EPUBs with no issues or errors. Only the master document fails to export. I am using the 184.108.40.206 Ubuntu version of LibreOffice on Pop_OS.
