This is the bathroom- What is your recommendation?

Painted less than 1 year ago.Spacecote kitchen n bathroom.Added test pot yellow acrylic myself.We don't have a steam vaporizer in the bathroom.I'm not sure but I'm thinking it peeled as the paint below maybe oil based.The top layer is water based or maybe I shouldn't have added the acrylic.What is your recommendation?Thanks in advance
