Take the Wheel Mfg Adaptors off
Take pictures of the bearings pressed into the frame.

When these steps are accomplished, you are well on your way to solving it.
Your bike shop tech is an idiot. He has proven that by what he did. That bike should have never left the shop without the crank arm bolt torqued to spec. Your spacing is too wide. It likely isn't the parts but you may have an extra seal or spacer in there you shouldn't have.
If there is no wave washer or no adjustable lockring for preload adjust...or...if not built to proper spacing which yours is not, then it is built improperly. You start by removing everything so we need to see the parts. Leave the bearings in the frame for time being.
