Parameters not being passed

Good afternoon,

I am using the plugin on my site to capture the referrers and information to better track google parameter’s and so on, I am finding though the referrers is always being kept blank which does not make too much sense to me.

I suspect it may be because someone browses to page A, and from there they go to page B (the contact page) and the referrer / UTM information is being lost, is there any way to retain this information.

Cheers
