Promis-e Terminal Manager madness

In the Terminal/Pin-Plug Manager (latest AutoCad Promis-e V8i) if I select all 15 terminals then in the left pane Properties, I click on Part Number(s) and assign a part, the Part Number column shows the correct part number....so far so good........but when I click on an individual terminal in that column and check the part number, only the part number and quantity show with all the other columns blank. I have tried with various different part numbers but still the same, I have tried a re-boot etc.

Any ideas,

Thanks,

Nigel.
