Here's my last post on this -
There's definitely something weird somewhere and I'm quite happy to accept it may be peculiar to my BSV.
In the configuration tool, when I set the presentation options for both attribute and for form, here's what happens:
When I set the Number of lines to 1, it displays as 1.
When I set the Number of lines to 2, it displays as 3.
When I set the Number of lines to 3, it displays as 4 and so on.
The Width(symbols) doesn't affect the presentation at all.
I'm going to live with setting my required three line presentation to 2 in the configuration too and setting the width by pixels. This works 🙂
All new attribute fields configure and present correctly.
