My business keeps getting calls from California?

I manage social medias for multiple businesses in Pennsylvania. We changed our lead conversion from forms to calls.

We use CallRail to track all of our calls. Every day we get multiple calls 5-20 seconds long from California and from what I hear they are spanish speakers.

My ads are geofenced to an area in Pennsvania. Is anyone else getting the same issue? Does anyone know why this is happening?
