Sidescroller Collision Issue

I have an issue with an object colliding with the player when it should only overlap in a 3D side scroller. I am a programmer that is fairly new to the Unreal engine and blueprints.

The SideScrollerCharacter has been extended to be able to equip (attach) a sword object and throw (detach and add velocity in the direction of the mouse relative to the player) the sword object. The problem is that when it is thrown, the sword will either go toward the target as normal or it gets stuck on the SideScrollerCharacter which either changes the direction it should go or stops it completely. When it is stopped, it seems to slide down the SideScrollerCharacters capsule component.

The Pawn collision settings have been modified to only overlap the Weapon channel and the weapon collision profile only overlaps Pawns. The SideScrollerCharacter capsule collision component and mesh are both set to pawn collision profile. The Sword object has a box collision and 3 cube components, all set to the weapon collision profile (which has the weapon channel as the object type).

I have attached images of the collision profiles as well as the SideScrollerCharacter and Sword functions. Can anyone see the problem? The project has been created in the 4.12.5 version of the engine.

Here is a link to an example project which shows the issue
