Q45- top clamp slipping

Getting my new Q dialed in. For some reason, the top clamp (the one with 2 5mm bolts on either side, which sets the handlebar height) keeps slipping. All the bolts are plenty tight and I'd feel any more would be overtightening them (I'm a fair bike mechanic).

The left side from the back of the bike) seems fixed and doesn't turn at all. The right is snugged as far as it will go. Is the left side key-slotted, or some other reason it doesn't turn at all? I'm thinking I need to disassemble it and check it out, but thought I'd ask here first.
