Controlling the radius feature so it doesn't affect adjacent faces

Hi all -
I am working on a model with several surfaces - I have two faces that have been knitted together and are perpendicular to each other (touching)...when I go to radius these,

the feature works - however it also rounds the adjacent faces of my model and I was wondering if there was a way to control this; I can delete these faces and rebuild them

but it seems counterintuitive and more work than it should require. If anyone has any advice I'd appreciate it.


I've attached two Jpegs - there first shows the line (in blue) I am trying to use the radius feature on

The second Jpeg shows what the Solidworks is indicating will be the result.

Thank you.
