Screen SO301000 added new checkbox to sales order line using the customization project editor. New field shows in column configuration for line in details tab. When the field is moved from available columns to selected columns and I click OK, the field shows on the line for a second and then disappears. I examined the generated HTML and I see the field there but the colgroup element for my column has a width of 0px?
I have reviewed all the layout properties and they look correct to me, must be something simple I am missing but I am a newbie. Thank you in advance for your assistance.

ASPX code for field:
<px:PXGridColumn AllowNull="False" DataField="UsrIsShowOnPrint" Type="CheckBox" CommitChanges="True" TextAlign="Center" ></px:PXGridColumn>
