If you're using the FP8 with Bitwig and the scribble strips do not show the tracks you're scrolling through, try using the "Bank" setting on the FP8.
This will change channel scrolling from individual channels to banking 8 channels at a time; it will also change the focus of the scribble strips.
This is just a function of MCU implementation in Bitwig and not reflected in other DAWs.
