EDIT: Actually I remember that the two souls were shown during Ichigo's Bankai training I believe,

The Zanpakutô filler arc is non-canon. Unless Kubo participated in its creation with canon details, it has nothing to do with the things that appear in Kubo's canon material.

Yes, the manifestation of Zabimaru was shown during Ichigo's Bankai training, and once earlier just before Renji broke out of his cell to go save Rukia and ended up fighting Byakuya on the way. But both times it was only 1 spirit in the shape of a baboon.
