Collision Responses will reset to previous setting after changing the Preset Collision Profile

Collision Responses will reset to previous setting after changing the Preset Collision Profile.

After the change is made and "Accept" is pressed, the Collision Responses will still have the old checkbox marked when the Preset is re-edited.

Frequency: 1 out of 15 times

User Description:

Often, it takes a couple tries for modifications to the trace channel collision response of a collision preset to actually change.

This behavior is consistent on two computers, both running 4.15. DefaultEngine.ini is writable.

1. Open QA-Game
2. Project Settings > Engine > Collision
3. Drop down Preset
4. Select the first preset "NoCollision" > Edit
5. In the Edit Profile window, change either a Trace Type or Object Type to a different checkbox
6. Select "Accept"
7. Select "NoCollision" again & Edit
8. If the correct checkbox is active, repeat steps 4-7

Results: About 1 out of 15 times; the last change will not be saved and the old checkbox will still be checked

Expected: For the change to be saved everytime
