Welcome to Marvel Fanon! There are a few issues so far with your pages. First of all, Earth-101 is not your reality, so you cannot add articles to that reality. On a similar note, you do need to choose your own reality number. Secondly, if you want your articles to be in the MCU, you can add the category Earth-199999, but Marvel Cinematic Universes is for alternate versions of the MCU. Thirdly, articles need history and content added them to stay up, not just templates, otherwise they can be tagged for deletion.
