Priority of layered Markers and Regions?

In this screenshot, I want the top region to be priority. So when it’s on this loop, the transition to region is priority. But when it’s on a different loop, the magnet region is the priority.

Currently, in this screenshot, when I select parameter 3, it triggers the magnet region instead of the transition to region, which is what i want

It may work as you intended, but the fact is just after it goes to the transition (at the right), it immediately goes back to the magnet region (without playing the transition).

True. I’ve solved this eliminating the magnet regions and using “transition to” timelines instead.
