Mode 7 (Hybrid Mask + Wordlist) only using 1 GPU?

Hey guys.
odd thing here, for some reason with using -a 7, only one GPU is active:

Code:

not sure why this is - everything else works perfectly, even if i simply switch to -a 6 and move the ?a to the other side of the dictionary path, all 4 GPU's work.

any idea what is the cause here?
thank you!

There is an asymmetry in left-hand-side vs right-hand-side work capabilities. See
