Reproduce with:

• Repeating Shot Infusion (Any item: longbow, crossbow 1h, 2h, etc...)

Repeating Shot description: This magic weapon grants a +1 bonus to attack and damage rolls made with it when it's used to make a ranged attack, and it ignores the loading property if it has it.

Checking the character sheet, this bonus to attack and damage rolls is not being added. It does, however, properly add it for the Enhanced Weapon infusion.

This is happening to me as well

Post links to your characters so the Moderators can look into it for you both.

 You aren't attuned to the item.

Repeating Shot

Item: A simple or martial weapon with the ammunition property (requires attunement)

This magic weapon grants a +1 bonus to attack and damage rolls made with it when it’s used to make a ranged attack, and it ignores the loading property if it has it.

If you load no ammunition in the weapon, it produces its own, automatically creating one piece of magic ammunition when you make a ranged attack with it. The ammunition created by the weapon vanishes the instant after it hits or misses a target.

Aha! Thanks, must have missed that.
