Problem with Filtering Schedulable Fields

Hi There,
I am really troubled with filtering the schedulable fields for my Key Schedule. As visible I have exactly the same names in my list and schedulable fields list, BlueSquares, but when I filter Just one of them appears in the result, Red Square!
I even tried to filter using string nodes instead of the list, but no better result.


Room Schedule Keys.dyn (51.2 KB)
I do appreciate if you could help me to solve this problem.

Best Regards,
Farshid
