This fix #1147 (closed),
An strip() function was missing. It was working with our examples but if a workflow had "test__test_test" instead of "test_test_test" (_ == {space} ) it was not working
This bug was introduced in 4.0.89 when this function changed to check each filter individually instead of the whole filter with an IN when treating with integers ( per example, 1,10,2,3. 1 is in 1 but also in 10 )
