Were the bb shell threads clean, chased, and faced (at least clean and chased)?

Seems you followed the manual pretty well to the letter. Also from their installation pdf

"The bottom bracket cage may be deformed or the supports are no longer axial. In this case, unscrew the left hand support, apply the threadlock, then re-tighten to a torque setting of 30N-m or 22.13 lb-ft."

Can you verify that your BB shell is okay?? Maybe it's worth a chase & face....
