Help needed with a continental cup

[OptimusPrime]

Attached is the competition I'm trying to recreate from fm20, but I'm having issues with when it's starting. It's meant to be a yearly comp, but since creating an testing I've had it be a season behind when picking qualified teams & now it has irregular gaps when starting. It went from 3 years straight with the correct qualified teams to a 3 year gap & then a 5 year gap & I have no idea whats causing it or how to fix it.

Any help is greatly appreciated.
