Cannot see shift rotation in shift calendar view

Cannot see shift rotation in shift calendar view

I have an issue with shift rotation. I tried to use it but failed to understand it thus far. For example, I've set a shift rotation to happen monthly. let's say in October employee A will work in shift 1, and in November, employee A will rotate to shift 2. After configuring the shift rotation, I expect to see the shift schedule to change for November. However, the shift for November hasn't changed in the shift schedule view. Is there something I missed here? I hope this will not be complicated.
