Since it's the "off-season" (yes, I know turkey hunting is coming) I would send the entire bow (minus scope) back to Excalibur and ask them to check it over completely, especially if this is a brand new bow.
Do this either directly yourself or the dealer you bought it from.
Excal should make it right and it will be easier if they have the entire bow instead of guessing.
For whatever reason, something clearly looks out of alignment.
