Document keeps recovering when saved.

MacOS latest and Libre Office 5.4 up to date. I have created a Writer document. Every time I close it and then later reopen it is goes into recovery which then recovers (or whatever it does) and I can continue. Is this a bug?

I’m having a similar experience. LibreOffice displays a document and asks me to attempt to recover it. The document is an Excel spreadsheet and it resides on a share. From Windows > Excel I open the document and it’s fine. Why does LibreOffice think this document needs recovering?
