Multiple of the same buildings in one city

Game: #5952549

While I as Equatorial Gabon was being attacked ordnance foundry was being upgraded, after I fended off attackers old building stayed while new upgraded version sprung up. Now I have 2 of the same buildings but different levels, there wouldn't be an issue if the game doesn't take the lower leveled building as the main one for calculating production times. I have ordnance foundry lvl3 and lvl1, I can upgrade to lvl4, but for production it takes only lvl1 building. Game is not frontline pioneers, it's normal team up event.

Images included.

I would appreciate it if it could be fixed as soon as possible as I need production speed.
