Xcode Push Notifications Issue

I'm currently trying to enable my Push Notification on my project but I'm getting this error

I went to my app ID and saw that it is enabled as well.

When I was looking at my certificated, I also saw that I'm getting a "this certificate has an invalid issuer" on my certificated that I created. Could that be the main source of the problem?

I would appreciate any insight and thanks in advance! :)
