File System widget not working after upgrade (OMV5->6)

I get the following annoying, but not at all serious, bug with the file systems widget after upgrading from OMV 5 to 6.

Any ideas how to fix this?

It's not the browser cache.

No, the file systems tab is also affected.

I had a NFS Remote Mount that stopped working due to newer Linux not honoring the noatime NFS mount option. This made all of the FS widgets bomb. I removed the mount option and all is working.
