Problem adding multiple sheets (Have to select sheet format)

I am having a problem when adding multiple sheets to adrawing. When I do so, SW responds with the message "The sheetformat could not be located". I then have to select it from thesheet format / properties box.

I want to automatically create multiple sheets to exactly match thefirst sheet. If possible, I would also like to have revision tablesinserted as per my current templates.

It seems SW uses the template file to create the drawing and firstsheet and thereafter it uses the sheet format file.

From what I can remember it used to work the way I want it to soI'm not sure what I have done to cause this problem.

I have looked at the system options (File locations and sheetformats) this all seems to be ok.SolidworksDrawings And Detailing
