That's almost certainly a side-effect of the PROMPT_SP option, see the
manual entry. This gets printed at the start of the line, then covered
over by the prompt itself.

Somehow in the case you're showing some output is coming out between zsh
printing the mark and printing the prompt itself.  I have no idea where
that would be, but the pre-prompt activities are carried out quite
early, before the line editor is set up, so there is a reasonable amount
of scope for it.

If you don't have time to track down where the extra output is coming
from, turning off the PROMPT_SP option should make the mark go away.
