The game says my restaurant is incomplete even though it's a finished build.

Hi there, I’m still a newbie but through endless research I found that using cc tables and chairs in the restaurants loads that error and says restaurant is incomplete even though I had everything on list. Try change your furniture to base game or Dine out. It is quite frustrating because the EA furniture doesn’t look great. I wish I knew this before starting a whole new save file. 

Hope this helps!
