Because it says "NOT all white dots are given", normal Kropki rules do not apply.
This happens for consecutive 2-3 cells which are XV variant V (listed) and also consecutive Kropki (not listed).
I had to modify SiSeSuSo a bit to neglect consecutive Kropki constraints, if not listed.
All is solvable without the killer cages and the outside sum-of-cells between 1 and 9.
Only KR (double or consecutive) and XV (sum up to 10 or 5) constraints are sufficient.
