Save button is not saving changes

I have a simple Opportunity detail view page with a save button in my page title component.  The page title component is related to the Opportunity object.  
Sometimes (not always) a user makes changes to the fields in my field editor component (also tied to the Opportunity object) then hits the save button, but the changes do not save.  The “saving” message appears momentarily then disappears.  The user then refreshes the browser and the changes did not stick.  What could be causing this?

This page has been working for years without issue.  We just switched to Skuid for Lightning Version 11.2.6.  We were not seeing this before that upgrade.

Can you share the XML and steps to repro?

Preferably with standard objects and fields so we can test it.

Do you want the entire XML from my page posted  here in comments?  That’s a massive amount of text.

Are you able to simplify it and post a smaller page? The shorter the better.
