Franchise room

what is prinicple of builiding the franchise room. I have 2 rooms not to far one ich other. First has 200 products sold, second has 4 products sold. Whats the problem?

It depends on the rating of the shop and the size/provided shelves. But may you can send in a bug report and write down the number here. Then the devs can take a look and may adjust the balancing.
