Is vent itself upright and pitched good. Is it old. Is it leaking at all. Try a different vent. The vent may be leaking just a trace so steam condenses in it, and fills to point that it floats your bottle up and keeps the vent hole sealed so vacuum can't be broken and let the water out. Some vents come with a sheet metal tongue inside the pipe thread to let water out while air/vacuum goes over it from inside. Inside the vent there is a bottle with a little fluid, probably alcohol that boils at about 170 and pushes out the flat bottom of the bottle and causes the needle on top of the bottle to seal the vent. The bottle will also float to keep flooding from leaking water out.
