Hi Sebastian & Frank
I'm sorry but this was two years ago and at another company, I can't even find any notes on it...
From what I recall though, it wasn't something I changed anyway, someone else made an adjustment whilst I was away a few days and I don't think we ever established clearly what is was! All I can suggest is that you review all related NWBC time parameters, as well as standard time parameters, and ensure that they are set appropriately.
Good luck!
Regards
Ross
