Just to make sure, this is the same frame you had the Red crank on, correct? same bb, same adapter, same exact setup...
Most all the Quarq cranks I've dealt with had 30mm spindles. if I were to guess, I'd say the wheelsmfg adapter is hitting part of the Quarq spider before everything tightens down. Try, with the crank off the bike, sliding the adapter on the spindle and see how far it goes on before hitting something.
Worth checking, as is adding a washer on the DS (which could address the same problem).
Unfortunately the Praxis BB30 adapter BBs are Shimano only. KCNC makes a GXP one but I've read a couple complaints about them creaking.. and the Wheels adapters I already have are lighter and worked just fine on the old Red crank. If I can just figure out why they're not working on the Quarq.
