Looking for Adobe analytics implementation expert. few tags are duplicating when user vising to site that means getting page views twice on a single server call. noticed that this is causing because of we implemented analytics and target using DTM on single page application(using salesforce). duplicating tags are page type, internal campaign, always do this and page load new, page name. all these are calling in pageload rule. how can I debug these tags. also in Adobe target getting some VEC selector error.
I'll appreciate if someone can help on this.

Thank you!
