Provider Info Overiding Custom Variable

Hello ,

I have a custom variable called Visitor-From. Basically for every visitor ip address, I am querying a service and retrieveing the organisation name or customer name associated with the IP. There is a possibility that sometimes visitor name might just be the ISP name. My issue is , the custom variable is getting recorded only if the value returned is non ISP name A.K.A organisation name. If its ISP, it is displaying it as provider. This is causing issue because provider variable will not be recorded under custom variables. I have attached a pic below for reference.

Any help is much appreciated

Thanks
