Hi ironsight design, is it possible for you to post the .3dm file or e-mail it to me at moi@moi3d.com if you want to keep it private?

It's hard to give advice without being able to examine the geometry.

But if you want to remove a fillet there is a new tool in the v5 beta using shift+delete.

Hi ironsightdesign, also you may need to select more edges for the fillet, it won't want to stop in this spot since that would open up a hole:
