I bought some used happijacs from a dealer that have the quick release.
These jacks are so well lubricated that the extension would start to extend on it's own from gravity when the quick release lever was activated.
IMHO, that's the way they should work.
Don't assume too much from the way it moves. Only one of my four jacks moves that easily right now. It's the only original one (now almost 4 years old). The other three I sent back to Happijac when they were 2 years old for a paint issue and they retubed them (free re-build for me :) ). When they came back they move much harder manually. My theory is there is more grease in the rebuilt ones than the original one. I'd be willing to bet the used jacks you got will need refreshing sooner than you think.
A couple of years ago my brother rebuilt his and had the same thing happen. More grease meant harder to move when released. I don't think that's a bad thing.
