TFB Scenario Design

[Red Lancer]

I am working on a TFB Scenario but am stuck on setting an Embarked limit - when I playtest and try to embark I am told on the bottom left dialogue that I have exceeded the embark limit. I thought that this would be in the pdt file like the rail value in PzC but if it is I cannot find it - in the stock France 40 scenarios I cannot embark but I can in the Norway scenarios and they both use the same main.pdt file. I have searched through all the menus and the manual and cannot find any hints. Can anyone help?

P.S. On the HPS website it states 'It also comes with an extensive historical order-of-battle and scenario editor so players can create their own scenarios'. I can find the scenario editor and a pdt editor but no OOB editor - is this a misprint or am I a dimwit or do I need to contact HPS direct. I can do it in notepad like the Napoleonic series but I'd rather not.
