Bathroom paint bubbling. How to fix this.

Decided to paint bathroom following a refurb. I had no idea if it had been previously painted with oil or water based so decided to use a primer. Walls & ceiling were sanded and damp wiped and left to dry. Primed with leyland acrylic primer & undercoat and left to dry for 2 hrs. Ceiling painted with Dulux bathroom soft sheen & walls painted with valspar standard bathroom soft sheen. I've scraped back bubbling paint it's peeling down to the primer & the primer is chalky(I can scrape with my nail and it turns to powder) For the most part the paint seems to be well adhered and it's just in 3 spots in having the issue I'm just not too sure where to go from here.
