A city that I received from my enemy in a peace treaty is not giving its base yield. (The 3 food and 4 production of the city tile.)

The 2 Hammers you see come from the walls.
I selected Puppet after the peace treaty that gave me the city and only later occupied it, but the problem existed from the beginning.
This is the only city with that problem - my capital, my secondary city and the conquered enemy capital all function normally.
This is with Gem 1.13.4 (Civup 2.5.2).
