Rolled Up bas appearing on the higher level Summary Bar

Guys

I have created a procurement string for each package. rolled up the bars so that each package can be seen on one line - I have used flags to determing the shape & colour of each individual activity within each package. ie tender information = flag1, tender period = flag2 and so on. This works fine, however, on the overall programme I have a procurement summary bar which summarises all the procurement activities. All of the procurement activitites have rolled up to this bar - looks awful. in the format bars section I have set the bar as Rolled up, Flag1 - if I take the rolled up off, it does not appear on the package bar. Any ideas how to get rid of the top summary bar showing the rolled up individual procurement activities (20x15= 300 bars!!)

In desperation Andrew
