You can't earn achievements - Read More - No settings to update.

My main world states I can't earn achievements, but it gives no settings that I can set to fix it.  The only change I made to the world was enabling an add-on featured on the marketplace.  The only reason I added it as I had read it would not impact achievements.  I have since deleted the add-on.  Link to the add-on.  https://www.minecraft.net/en-us/marketplace/pdp?id=181c5ffd-a694-4418-9d46-969903678d13

How do I fix this?
