1st picture: Invert order not enabled - unlocked

2nd picture: Invert order not enabled - locked. Its working as intended

3rd picture: Invert order enabled - unlocked. Ice barrier looks like it have switched position correctly.

4th picture: Invert order enabled - locked. Once locked ice barrier no longer appears at position 1 but instead went to position 42.

When unlocked and invert order is enabled it looks like it is working as intended. When the frames get locked it reverts back to how it was with invert order disabled.
