Welcome to the Q&A Forum

No that's not normal and it means you are internally linking to campaign tag URLs which is probably also causing loads of data pollution in GA For something like this, I'd expect it's an infinitely-recursive URL nesting error or something like that. A client of mine had a similar example lately, they had URLs like site.com/fr/product and you could click the flag in the nav to change language, for example ending up at site.com/en/product (English instead of French) The problem was, if you were on EN and you clicked the EN flag again, it would go to site.com/en/en/product (infinitely adding to the language layer). Errors like this on cookie-cutter, cloud-managed sites are very, very common (their tech teams often aren't fantastic to be honest)
