Just upgraded to 2016 and was looking forward to making some better property tabs but...

Working on weldment properties..  I've added some text properties, using a text file to make a list.

Whilst testing on a simple part I can apply the properties, but the tab doesn't read them back,,, the list boxes remain blank, which makes the whole thing reasonably useless.  The description and the comment populate back, so it must be something to do with the list.

Here's the setting in PTB

What's worse is when I add my Weldment Cutlist Template into the Weldment Properties so I can see everything there, crashes every time.

Is this the behaviour other people experience or am I doing something wrong?  Is there an alternate way that works, I went for separate text files instead of an excel file thinking it would be faster.

Thanks
