Foliage scalability does not accurately update when settings are changed in game

There is an issue that occurs where changing the scalability settings via the game script during play saves the values for the editor, but when the game is played a second time, the settings visually revert but then do not change when the script. This issue is not a regression.

Versions Tested: Issue occurs in all versions
4.16.3 - CL: 3561208
4.17.2 - CL: 3658906
4.18P2 - CL: 3660543

1. Open the project attached
2. Under the settings ( the option above the viewport) select the engine scalability settings to make sure all settings are set to epic
3. PIE (make sure it is a new window)
4. Press the I key once (a print string should display a number)
5. Press the I key a second time (expected result)
6. Exit the game and PIE a second time (the scalability should have reset)
7. Press I Key twice so that the window resizes a second time
   Result: The scalability does not change
   Expected result: The Scalability should change
