"Circling Aircrafts" problem in composite flights?

This is a strange situation found when building the Operation Opera 1981 scenario.
In the historical Operation Opera one of the flights was not 2xF-15A, it was 1xF-15A+1xF-15B, a special F-15B with a undisclosed type of offensive ECM.
My idea was to simulate it with a "composite" flight with a F-15A/B Baz 81 and a F-15A/B Baz 85, the late equipped with a stand-off jammer.
No problems apparently programming the composite flight from Etzion as Long Distance Air Patrol.

But when playing Red side to verify the programmed Long Distance patrols worked fine when Blue side is played by IA, all the other programmed behaviour as programmed, but the composite flight is keep flying in circles over its airfield!

Also, if playing Blue side I manually set the same composite air patrol of F-15A/B Baz 81 and a F-15A/B Baz 85 the outcome is the same, both aircraft don't go to the patrol zone, and keep flying in circles over the airfield!

Later I saw the behaviour is not apparently generated by the composite flight, as forming the patrol only with the F-15A/B Baz 85 (57255, classified as "intercept", as in the F-15A/B Baz 81, but with ECM).

You can reproduce the events with the attached scenario test file.
