Why are my nominations being approved and not put into pokemon go

It says that it's approved and used in another Niantic game im nominated it because I play pokemon go and so does everyone else in my town.
So if my nominations are gonna be used elsewhere then why bother nominating stuff

Each game has a proximity rule that determines whether new wayspots can be added to that game. So if you're nominating wayspots that are in locations that fail the proximity check for a specific game, that's why they won't show up in that game. If you want to learn more about the system Pokémon Go uses, look up the Pokémon Go Hub guide to S2 cells.
Hello and Welcome @JTET11-PGO
To add to what @HankWolfman-PGO has said if you would like to provide 1 or 2 of your wayspots we can explain further. We need the title and the exact location- full address or coordinates.
I have one pokestop with The same problem... how can i solve this problem?
@willcamelo-PGO
There is probably no way for it to appear, but if you give us the details - title of wayspot and exact location. - we can check what the situation is.
I have an example Retro tech Repair in Carlton GA my brother nominated it and it was accepted, but never implemented on pokemon go.

Unfortunately it shares the same cell with Comer Centennial Time Capsule so it won’t be able to appear.
