Is the 18's causing the 10's or vice versa?
18's are such a pain because of all the contacts involved. Auxillary of M comes to mind. Plus all those contacts and the related circuits between ST and P.
As far as the calls firing.
Check on service tool Debug, motion excuses, and Debug, dispatch mode. If all proper check I/Os with tool. Maybe some inititation into a weird service may be happening in this version of software.
Good luck.
