The problem is that the same folk post the same problem on many fora, giving the impression it is a widespread problem when in fact it is likely local to one or two folk. Other folk are reporting no problems with ECoS but there is this programming short, which is odd. You should get an indication of a fault (usually loco wiring) on the prog track but the short duration and limited potential of the signal should not trip a controller.
Regardless of that Hornby will be looking at the problem next week when they drag their dusty ECoS out of the cupboard, where it has been since last testing when nothing untoward was seen.
