Pivot Offset Module does not respect on/off toggle

Toggling the Pivot Offset module in a Cascade Particle System has no effect on the particle system's position.

Tested in 4.20.3 (CL - 4369336), 4.21.2 (CL - 4753647), 4.22 (CL - 5439949), 4.23 (CL - 5501347)

1. Create a Blank project
2. Create a Cascade Particle System
3. Add a Pivot Offset module to it
4. Change either the X or Y values
5. Turn off the Pivot Offset module

Expected: The position of the particle system would reset

Result: The offset position remains the same
