Traffic sources no longer showing in Analytics, it says "forms.zohopublic.com"

Hello,

For some time now Analytics is showing our traffic sources as "forms.zohopublic.com" for all those visitors who fill out zoho forms. This means that we cannot see what traffic source generated these forms/conversions. It used to work before but now something is throwing Analytics off. Can anybody help? To be precise, if someone comes from, say, google adwords, then fills out a zoho form, analytics shows that this person came from "forms.zohopublic.com / referral" and not google adwords.
