SIMS.NET Timetables

[BadComputerDay]

A timetable has been put in the school's system using T6. Subject teachers have been coded as 'main class teacher' and support (EAL staff) have been coded to some of the same classes as 'class teacher.' Unfortunately altough everything is fine in T6, it isn't in the SIMS.NET timetables. On the pupil timetables in SIMS.NET if a support teacher is timetabled then they appear as the main teacher. Everything in T6 is fine. However this problem is compounded by the fact that we use BROMCOM which is lifting the same data as SIMS.NET pupil timetables. Have contacted local team, and BROMCOM but cannot get an answer. Help please!
