Upgraded to 1.15.4.994, PMS can't see Media Directories

[Kurtski25]

Server Version#:1.15.4.994
Have Synology DS416play. All was running well, until I upgraded. When I try to play anything, I get “Playback Error: Please check that the file exists and the necessary drive is mounted.”
The library paths are correct - nothing has changed from the 1.15.4.993 release. I then tried creating a new library, and when I try selecting { /volume1/video/Movies}, the PMS “Browse for Media Folder” action only allows me to see {/volume1/video/} It will not even let me select the /Movies directory.
Any ideas? The media is all there, just can’t point PMS to it.
