Some Edited Photos don't Upload to Smugmug

Question

I'm having issues with my edits not uploading to SmugMug (only on some photos, not all of them)
Lightroom Classic 14.0.1, Windows 10, SM Publisher Version 3.5.7.0, Lightroom 14.0.1
 
 I believe Smugmug gave up last night after 2 months.

Smugmug:  The Publish manager and Export settings windows appear to be correct. ⬆⬆The problem you are describing is an issue between the Develop and Library modules. This is out of the scope of the support SmugMug can provide for Lightroom.  I would check to make sure the .XMP files are associated with each image. This is really a issue for Adobe as the plugin takes instruction from the Lightroom catalog. N Data is stored or saved in the SmugMug plugin.
What's happening is crazy. I can upload anywhere between 10 to 100 photos, but there's always a few edits and titles that don't upload. I always go from LRC to SM plugin to my SM website. I always thought it was random, now I believe I've isolated a single picture that is problematic. Can someone provide advice or should i go directly to Adobe LR. I firmly believe I'm the only one with this issue. 
 
Sometimes if I go back, Click Republish & Publish it, the edited photo is now in SmugMug.

(only on some photos, not all of themAnd when you are in the Library Module, and look at these images in say grid view, they do not show up (indicate) as missing?
