DnD Beyond Maps Condition Icons Not Removing On Monsters After Toggling Off.

The new DnD Beyond Condition Icons are great, however I have encountered a bug that affects monsters only. 

When applying a condition to a monster, it shows up as an icon for my players - lovely, working as intended. However, if that condition is removed (say, prone for example) the icon itself does not disappear and it locked to the "on" status. 

I turn it off on my side, however it stays perpetually "on" on the players side, showing the icon in error. 

This is easily repeated and replicated, however i have not found any work around other than not using the new icons, which is a shame, because they are very good. 

Is this bug known?
