No it is not a bug. If user provided a disk to dss which alrady has signatures
from other tools, we will not use that disk for thin pool. One needs to
wipe all the signatures and then provide that disk to dss.

dss being a service does not mean it will automatically wipe off any
exisitng signatures on disk. It is very risky. I am not sure why are
you taking it so lightly.
