Why?

hello editor..
I want to ask, why when creating or editing a new/old geometry always fails even though it is in a bright area not dark?
for example I update one of the old geometries, namely adding a road name, changing the road type and correcting the geometry shapes (1 segment 4 points or more) when I click save a notification appears that it failed to save “does not have access”. but when 1 segment 1 point it works.

Please provide guidance and explanation regarding what I experienced.

Thank you in advance
