I noticed on my Grundfos booster pump that the rotating indicator is yellow, I thought it should be green. Does this mean there is an issue with the pump?

Grundfos model# and how old is the pump? Generally the arrows rotating/solid color should be green indicating no "faults" with the pump. Yellow means its a warning alarm and there was some kind of issue that occurred or is occurring. If you have the pump dongle connect it via infrared or via bluetooth with the grundfos app to determine what the alarm is.

I had this when the pressure sensor failed. It was MarCor that helped me troubleshoot. The sensor flow was clogged with hardness scale and once replaced the issue was resolved.
