Interface and the Utilization function in the Timeline view

Good Morning/Afternoon

I have inserted a timeline view into my interface and when I apply the utilization function to the timeline view it does not stay once I click out of that interface. I also tried to just copy the timeline view from the base instead of creating it within the interface its self and it does the same exact thing. Does anyone know how to fix this or is this just a bug in the system?

Thank you
