Most likely your browser has cached the tile images, if you view the base image and ctrl+shift refresh it the name might appear, alternatively you can add /dirty to the end of the tile URL and the server will refresh the cached image on the server.
In general it should be no more than about 5 minutes after uploading changes before they will appear on the server.
The 5 minutes are not always true. A simple change like a added name to a street takes longer because it doesn't trigger the fast rerendering.
It can take 1-2 weeks if you only change the name
