Bug. Can't build district

Hello everyone, tell me for what reason it is impossible to build a campus or in general any area in a place where there are stones or any other resources? There would be an excellent campus at +5, but something is some kind of nonsense. Usually it suggests deleting a resource, but there is some problem. In 3 cells from the city and for some reason it is impossible all the same. The situation is similar in the second city. Both of these cities are on another mainland, different from the capital and other cities where such problems are not observed. Maori civilization, maybe something affects.
