No "Fortify Until Healed" button for workers in cities

[GAGA Extrem]

If a worker is place in a city, the "Fortify Until Healed" button will disappear, so you have to either set the to Fortify manually (F) or skip their turn (SPACE). Outside of cities, it works fine, though.

Screenshot added to demonstrate the issue:
