Could you please post the .3dm model file? That helps a lot to examine what you've got more than just a screenshot.

Probably the filleter does not like the edge that is pretty close to it - the one that is in the middle of those 3 curves that come to a point. One of the biggest problems with the filleter currently is that it will not cross over an edge like that so you have an edge really close to the one you are filleting, you tend to be limited to a small radius that doesn't make the fillet run into that other edge (that is kind of running parallel to the edge being filleted I mean).

You can alter a loft surface after it is created by adjusting its input curves... But if you do some kinds of operations on the loft like a trim or boolean that history connectivity is broken, so you generally have to do that pretty soon after you do the Loft.

I am going to be working on making a deeper connected history in the future though.
