Easy fix and it doesn't cost a cent.
Shrader inflators are nmade to do 2 things so air flows. The valve depressor in the chuck opens the valve, and at the same time opens the hoses valve so air can flow.
These chacks are all designed around a valve needle that ends just short of the top of the valve.
I suspect your adaptor it sool long, something easily fixed with a file. When the adaptor is on the tubes valve should be just below the rim.
Now, don't forget to unscrew the little nut so the chuck's valve depressor can push the PV in.
