It is quite possible it was bled, but more air collected in it after.
With a fresh fill of water it can take some days for all of the air to
come out of suspension. The other possibility is you have insufficient
(or no) corrosion inhibitor in the system and what you bled was hydrogen
gas produced as a corrosion by product and not air.


But would all the air be in only one rad if that was the case ?

That is quite often the case - often the highest rad in the system, or
the first one etc, but it seems common to get one that favours
collection of gas more than the others.

There was sufficient inhibitor put in the system as I was there when
it was put in and know how much of the container he used .

Jolly good. At least with sealed system then you won't have any problems
with pumping over which can draw more air in.
