Rifles are offset in Display 1.15 when opening Content Examples Animation map

REGRESSION: Yes
WORKING: 3172292 (4.13.2)
BROKEN: 3177600 (4.14)

In the Content Examples Animation level, at Display 1.15, the rifles are offset from the character's hands for two of the skeletal meshes (green and blue).

The user can reattach the mesh, but if the user saves the level and loads it up again, the rifles will be offset again.

1. Open Content Examples in editor.
2. Open the Animation level by double-clicking the level asset in the Content Browser.
3. Navigate to Display 1.15 (Retargeting + World Interaction).

RESULT:

Rifles are offset from the hands of the green and blue skeletal meshes. Reattaching does not fix this, and reopening the map just breaks it again.

EXPECTED:

Rifles to be correctly in their hands.
