ᐅ Heating system gurgles despite having an automatic quick air vent

Our heating system makes loud gurgling noises several times a day, even though we have an automatic air vent at the highest point on the upper floor (its black cap is loosely turned).
Does anyone have an idea what the problem might be and how to fix it?
1) You can’t manually bleed automatic air vents, right?
2) Is the problem that there is air in the heating system that isn’t escaping through the automatic air vent (because it might be faulty)? Or is the problem that the automatic air vent works but in certain situations sucks air in? In that case, I would need to turn off the heating system and, after some time, close the black cap before turning the system back on.

Don’t the two manifolds have air vents like the radiators?As mentioned above:
“I hear the gurgling most clearly at the two manifold boxes on the ground floor and upper floor at the upper of the two horizontal pipes. The two automatic quick air vents are also installed on these horizontal pipes.”
