Right. Quicker than I thought. Importing gedcom created by PAF
1. The 42 date errors that I thought were not, were not reported. It did report three extra date errors which were 100% legitimate.
2. My relationship to the Home Person is the same as that in the direct gedcom test.
3. Top Tree Werret correctly has the two notional children fro the DNA linked branches.
The evidence points to Pam's problem stemming fro the import PAF routine.
I don't know whether it is down to my inexperience with PAF5 but when I chose the export to PAF5 option, the method was gedcom and not PAF format.
