Not reading source and Medium from Google Analytics

I have a form, https://www.frogproducts.com/frog-test-strip-giveaway/ and when completed I see the conversion as submit.jotformpro.com / referral instead of my set up source and medium?

Any ideas how to fix this?

Please try adding the following addresses to the Referral exclusions:

submit.jotform.com
submit.jotformpro.com
submit.jotform.us

Additionally, you may try adding ?utm_nooverride=1 parameter to your form's Thank You Redirect URL.
