Roads, areas and points not visible in some layers

Hello,
I’m new at openstreetmaps. I heard about this recently, so I decided to collaborate mapping poor towns where I used to live using the new ID editor.
The question is that every road/area/point that I’ve created is visible in some layers but disappears in other ones. What was my mistake?

Thanks

You mean in the different zoom levels when viewing the rendered map? That is normal, you don’t have to worry about it.

Nice to see you’re mapping in The Dominican Republic.
