When blending two Blendspaces that are in the same Sync Group and are utilizing root motion, scaling issues occur in the AnimBP preview. This only occurs when "Process Root Motion" is enabled
1. Open the attached project
2. Find the "BlendByBoolTest AnimBP
3. Open it and go to Show>Process Root Motion in the Viewport
Results: Strange scaling when the blend occurs. Does not occur in game (PIE to see)
Expected: No scaling.
