Custom Office for Work Ticket Templates

Just discovering the power of Custom Office (I'm a newb). I am running into a wall with one particular item. I have worked my way through creating user defined fields and tables and can successfully customize panels in screens and modules, but I'm stuck at setting the defaults for certain tables.

The one I am struggling with now is the Work Ticket Template table. We have Sage 100, 2019, Manufacturing and I cannot seem to set the Scaling Method in the Work Ticket Template Maintenance screen.

I get to Custom Office/User Define Field and Table Maintenance/JT Work Ticket Template/Advanced Field Settings and Add a field for the Scaling Method. There is a drop-down menu in the panel for Scaling Method and I want to change it to "Production Run" (the default value is No. of Parents per Template). The problem is, the drop-down in Custom Office has nothing in it, and when I click the Caution Triangle, I get the dialog "The Default Value for 'ScalingMethod' may be overwritten to "Y" by the business object." I'm not sure what that means or what to do about it. I have 2 screen shots below for visual reference. Any help is appreciated. I'm sure I'm just missing a step.

Thanks!

This image shows no options in the Scaling Method drop-down.

This image shows the dialog I get when I click on the triangle.
