Is there a work-around for Libre Office Writer will not view sub-folders on NAS?

My Office Writer running on Ubuntu 20.04 only goes down a few levels of folders on my Synology Diskstation NAS where my My Documents folder is. The Ubuntu Files app can browse to them with no problem. I have NFS enabled on the NAS. Would there be a way to mount the NAS drive/folder instead of browsing to it in other locations? VERY annoying bug.

Solved. When I looked, there was an NFSv4 sub-box under NSF, so I enabled it. This problem ended when I enabled NFSv4 in Synology DSM. I’m not sure if that was the cause or whether it was only correlation.
