Gmail will definitely not do this by default, only if you explicitly
tell it to do so using a filter. The exact behaviour will depend on
whether the filter is in Gmail or in Evo. If it's in Gmail, my
understanding is that it will fire as soon as the message arrives in the
Inbox, which is before Evo gets a chance to see it. That could explain
what you're seeing, but I would expect it to apply to every message, not
just some. OTOH if the filter is in Evo itself, it will fire only when
Evo sees a message it regards as new (which is *not* the same as
"Unread", see below).

Remember that Gmail doesn't really have folders, just labels, i.e.
"moving" a message to Inbox is just changing a label. It's not a new
message even if it's marked as unread, and I'm guessing it doesn't have
a new UID (Unique IDentifier). Using POP, Evo will only consider as new
messages whose UIDs it hasn't already seen. (This is hypothetical as I
don't actually know how Gmail handles UIDs.) The question then is "why
does Evo think it has already seen these UIDs?". That might depend on
exactly what your filters are doing.
