breakage on the step of my plaster pool

[socialvista99]

The other day I found while swimming that my plaster pools step have gotten these breakage. I think it's there for a while but need to make sure things are right and I am doing my due diligence. I have learnt alot from this forum so posing the question for experts opinion

The plaster is damaged by something hitting it, or it’s failing. You can have someone patch it if it’s relatively new, or replace the plaster if it’s failing like that in multiple areas.
