University Commons Food Stall Issue

So my two Sims who are cousins were at the Commons at UBrite. At first visit the food stall inside worked as usual, then on the 2nd visit and so on, nobody showed up. I figured that the smaller stall outside of the building (selling breads & coffees) took priority of who the vendor manned so the indoor Commons stall lost out.

Is there any way to reverse this? I can't pick up the outdoor stall as it's out of bounds, and selling then replacing the indoor food stall didn't work either.
