Regression of CanJump Function not being accessible in blueprints in 4.8

When trying to override the CanJump function of a character blueprint, the function does not show up in the MyBlueprint panel's function section. Hovering over the Function bar shows the "Override" option but CanJump is not listed.

Regression Point:
In 4.7.6 binary (CL 2513093) the CanJump function is listed in the Override options.

Promoted build from 4/23 (CL 2521032) the CanJump function is not in the Override options.

1. Create Third Person Template project (code based)
2. Open the Third Person Character blueprint
3. Hover mouse over Functions in My Blueprint and choose Override

Result:
CanJump is not listed in the functions available for override

Expected:
CanJump was present in 4.7.6
