top of the house air building up

Hi, I've noticed lots of air building up in the 2 attic room radiators. I was having a high pressure problem but had the system serviced and hoped the problem would go away.

The weird thing is that if I bleed these to rads every other day (after about 4 days, they are almost half full of air) for about 2 weeks refilling and getting it to about 1 bar, the problem goes away.

Any ideas what the problem could be?

Thanks Paul
