My example is on the acquisition page but I am pretty certain this bug is common throughout majority of the analytics page.
Whenever you remove your annotations, upon trying to re-select more than 1 causes a strange bug. I tried to select Thumbnail and Icon but I could only choose one or the other even though by default both are selected.
Selecting Icon, then selecting thumbnail. This seems to deselect icon as shown in this video:
You can fix this by removing &annotation=PlaceIcon
from your url which will default back to Thumbnail and Icon being selected.
