The plasterboard is sucking it in. Try apply  a coat of PVA and after carry on with the paint it will work

Are you letting it dry enough between coats.
If it continues let the wall dry.
Then PVA it let it dry coat it again should be fine.

What paint are you using, it cold be that if paper was in before or try stain block then give it another coat or 2 hope that helps

Make sure you dilute the paint it will seal the plaster, then you can put the undiluted paint on second coat and then a final coat.

You could try applying a product called shellac first, which is also a stain blocker.

It shows that the plasterboard is sucking and always you will get a good result, if you are painting in a dry day and keep inside temperature +18 and above. PVA it let it dry coat it again and will get the best result.
