find the displacements brushes you made.

and on those brushes there will be No Draw textures on some of the sides, which is not allowed

simply go into the displacement editing and click on those sides of the brushes and hit delete.

when making the displacement brushes make sure to highlight only the sides of the brushes you want to make displacements
