There is a list of which cities can convert in the first post of this thread.
Any known way to reverse it?

The final farm building is available when no Nomadism culture is above 50%, and after it builds, then you unlock the 'convert to city' building. Most likely you still have > 50% nomadism in the province and can't build the final farm. This information is provided in the building description of each farm, at the end.
Here's some images from Palmyra, especifically its population stats
Its agricultural buildings
And agricultural building browser (though it seems doesn't match)
So what do u advice to do?
