Confusing Slide the Green Tab on Drum Unit MFC-9340CDW

I recently experienced a Slide the Green Tab on Drum Unit on my MFC-9340CDW, and what’s confusing, the error message lists all the 4 cartridges, and no mater how many times you slide and return the tabs back to the resting spot it doesn’t resolve it.

But I thought I would try resting the tab to the right instead of the left and this solved it surprisingly.
