Your problem
My problem is: Just to let you know the ‘operator’ does not work when you create a segment via the api in version 3.3.3. I upgraded from version 3.2.1 and the operator works fine. In version 3.3.3 the only operator value accepted by the api when created a segment is null - all other values are rejected.

I am happy with version 3.2.1 but was thinking updating to version 3.2.5 - does the segment api fo 3.2.5 does anyone know please.

These errors are showing in the log:

Steps I have tried to fix the problem: Tired various previously accepted operator values (3.2.1) but all fail on version (3.3.3).
