I wouldn't know about drying out that quick, but if they were already aging or dirt getting inside. Seals do shrink and if disturbed sometimes will not seat again properly. Is the shop telling you that this is the norm? Call Newell and see what they tell you in the service department as they know that system inside and out. And please report back your findings.
Hopefully, we can help you get things resolved around here.
In the past I completely redid an air system replacing all the hoses and brass compression rings from one end to the other, but only because I wanted to have everything new on a aging unit.
