Metadata badge is not updated after the metadata is updated

I've been fighting this, and hating it, for years. I'll add that I've gone to great efforts to make sure that the file server that holds the image files and the workstation that holds the Lightroom catalog (and on which I run Lightroom) are synced to the same NTP server, so their idea of time is synced down to the millisecond. (In my case the fileserver is a TrueNAS box. The files are shared via SMB. Both synced to an NTP server in my server closet at home. Since people not using fileservers have the same problem I don't think that's the root cause of it.)

Several of us have noticed similar symptoms in LR 10, where Save Metadata To File doesn't update the metadata status correctly:

I would like to add something more. This morning, I verified that the metadata is being updated. I opened Windows Explorer and viewed "details" on the files. I saw that the "last modified date" actually showed the DNG files were modified yesterday. However, the badges still displayed the down-arrow. I pressed the arrow again, saw the progress meter as mentioned in original post. Then, I looked at the files again in Windows Explorer and saw that the files were modified this morning at the current date and time. As an IT professional myself (ret.) I know that consistency of problems helps. However, I went to another file with a down-arrow, selected it, saw the progress meter, looked at the file in Windows Explorer, saw the details that the file was updated on the current date and exact time as I hit the down-arrow.  Then, I returned to LRC to look at the image, and...the down-arrow had (properly) disappeared. This file was also a DNG file. So, what was the difference between these files?  Answer: the one that worked had been edited in LRC!  Ok, so I tried another file that WASN'T edited in LRC, and repeated same process. The file's details in Windows Explorer showed it was modified on the current date/time. Yet, the down-arrow was not changed. I currently don't have another image that I worked on in LRC, as I'm returning to LR after a bit of time, but I suspect the metadata badge would display properly. At least, my research gives the developers something to think about. By the way, I synchronized folders before ANY of this was done. In fact, since I had done considerable changes to folder structure and moving images around in BRIDGE prior to accessing LRC, the LRC catalog was all screwed up.  I deleted ALL LRC catalogs and related files, and indicated LR should create a new catalog, which it did. But that creates a new question, and new post...
