"If that's the case, out of curiousity why there has been numerous reported cases of people that catched covid again after already recovering from it?"

There have been many, many news articles that speculate about this, but to date, I'm aware of two papers that document re-infections. Both papers isolated and sequenced the viruses involved, and both papers documented re-infection with significantly mutated variants of the same virus.

Yes, here is an example of a paper that mentions a re-infection with significant genomic differences between the two samples: https://www.thelancet.com/journals/laninf/article/PIIS1473-3...
