Amylase is used commercially in quantities measured in parts per million. You probably still had enough for starch conversion. There is no telling how much is in these yeast balls.
I have never seen any indication of mold and since I shake mine often it would be hard for mold to grow as mold needs to grow undisturbed on the surface.
Ive done both shaken/stirred batches and the undisturbed batches are far superior and that includes mold on top
