BUG -Thumbnails no longer showing

[KickingApps]

None of the SharePoint thumbnails I am referring to in my formula are showing up.  I did not change anything in the app.

When I look into the collection, the reference to the thumbnails are not there.  

Is this a bug?

Anybody?  Really would love to move forward on this feature but stuck.  Would love to know if this is a bug or creator error?  Not sure how though (creator error) because this was working fine all week.

I resolved by creating a new library in SharePoint.  Annoying to say the least.
