UPDATE: Included the .blend file:
Blender novice here. I'm trying to model a kitchen sink and i'm having an issue immediately with trying to bevel a certain edge. I've looked through various of the suggested questions/answers but it didn't really help me. This is the sink i'm trying to model:
I've created the basic mesh in blender as shown below:

Wireframe view:
I'm trying to bevel the edge as shown below but the beveling doesn't seem to happen along the expected edges:
By contrast, when i attempt it on one of the other edge, it seems to happen as expected:
I suspect it's not working because there are additional edges/vertices that i need to be taking into account or including at the bevel attempt? Could someone assist?
Many thanks!
