Corrections only on highest level of zoom

Hello all,
I’m new to OpenStreetMap and have just started to make corrections associated with our property and access roads adjacent to our boundary. I saved the changes and uploaded successfully, but as soon as I start to zoom out the corrections are no longer apparent, i.e. the details revert to to how they were before i made the corrections.
I’d really like to understand what I’m doing wrong before I continue making corrections, so any help or advice would be greatly appreciated.
Thank you in advance.

You didn’t do anything wrong. The render servers just didn’t get to create new tiles for lower zoom levels yet. What’s in the database (the objects you see in the editor) is not directly reflected on the map. Just wait a bit more.
