Answer 1

I had the same issue, and changing the facebook pixel initialization tag on GTM to "once per page" did the trick.

I know someone already answered that, but since that are more than one solution provided and the "selected" answer seems, to me, more complicated than this answer I thought i would comment here so that other people with the same problem feel confident to try this simpler approach.
