Why I cant see the same data on different PCs?

BUT on my PC (localhost) and server(internet)

1. Maybe the code on your server is not updated. Or, if it updated then your strapi was not restarted.
2. Maybe you use two different databases, one on localhost and another for the server.

I get all the data that I want, but I get old fields too (but I guess it is something with the DB).

You should delete the fields from the DB columns directly.
