I'm not sure what's wrong... I'm using the Killer layer every time, and works for me.
I go to Design -> New Grid -> Design and then select each 4x4 cage and press C to set the sum, as simple as that.
I'm using JSudoku 1.5b2 with default preferences.

I can confirm the first one has 1 solution.

I'm doing just the same!!

The problem is in fact more fundamental - forget the overlapping cages, it won't let me set any 2x2 cage with sum = 10-11, or 29-30.

And for sum = 12 the pencilmark display shows "1245" only, but should include "36" of course. It's the same for sum = 28, pencilmarks show "9865" but not "74" ...

OK, I fixed it ...

I looked at the registry and found a key which had value "all-non-cons". The penny dropped, you can't make a 2x2 cage with sum 10 or 11 in NC mode!

So I deleted that key and that fixed the problem. Not sure how I got into that state to begin with, but I was fiddling with NC puzzles at some point.

All good now.

Both are unique
for JS the first one uses 27 fishes the second does not solve
