I recieved my Ronin a couple weeks ago, and I have a question about how to adjust the roll axis. For some reason, simply loosening the 2 front lock knobs does not allow me to move left and right. I have to also unlock both side clamps (normally used for tilt axis). Once both of the front lock knobs and side clamps are unlocked, only then can I move left and right to adjust the roll axis. Is this normal? Everyhing I've read says I should only have to unlock the 2 front lock knobs, but that is not my case. Has anyone else expereinced this issue or is this normal?

It's pretty strange, normally the base is loose when you unlock the two front lock.
Could you provide a video link here?
