You may have problems if you used an expansion anchor in the CMU. I had a structural engineer long ago say that hollow CMU can not take expansion anchors. We had to drill the hole, fill with epoxy and set ATR studs in place. That had to cure. Then we could attach the steel angle brackets.
Could that possibly be the issue he has?
