Hi Tiler_Burden, 

This was a two-step fix: first update the building to its current state (no longer three separate buildings) based on BAG, which is done in:

Then I've removed the shops that aren't there anymore (confirmed by my survey and your photo), which is done in this separate changeset:

Which resolves this note. Thanks for reporting! :)
