Fan control during bridging

[Backbone]

Mattercontrol newbie here.

Use 1.5 vesion.

Choose to use it over Cura as it has fan control for bridging.

I need bridge fan control only for PETg printing.
But sofar no coller fan running during a layer that need bridging.
Option is marked.

Is there a setting for a minimum distance that this option is not working?
