Pertmaster - Problems with Demote (Indent)

I’ve just "inherited" a programme in Pertmaster and is now going to add some delays events here and there, however, I’m not allowed to demote/promote tasks (i.e. create summaries and sub-summaries)before all filters and sorting options have been set to certain values.

The problem is just that I don’t have any filters or sorting options applied so there is nothing to tick or de-tick.

Have also tried to set all present filters and sorting options, even though not applied, to the required values, but to no avail. Have also tried to delete all filters and sorting options in a copy of the programme, but still nothing to do.

Anybody got any ideas how to solve this in Pertmaster?

Thanks,

Bo
