Switches with fades overlapping in game

Question

I've built an ambiance system with switches, where some of the elements are simple sfx in loop and others are Blend Containers with an ambience bed sfx in loop plus a sequence container (that picks silence and then random elements that need to play occasionally for that ambience).
The switches work fine in game until I try to use fade in/out for each element in the Switch Container. For such case, the ambience playing does not stop when the new switch is triggered resulting in ambiences/switches overlapping (after the fades).

Looking at the Profiler I've noticed every time this happens there's a notification saying 'Fade aborted'. Not sure if this is associated with the error though.

Does anyone know what could be happening here?
