Sub-classed controls - show properties on Inspector panel - how?

I’m returning to a project (and Xojo, yet again) but for the life of me can not figure out how to display user-defined properties from a sub-classed text field to display in the Inspector panel associated to my sub-classed control.

As can be seen in the image under Behavior the last five items are my sub-classed properties, there are two others not showing which has baffled me, can’t see where the setting is to display the properties.

Any help appreciated.

Right click on the class in the navigator and select “Inspector Behavior…”. You can toggle the visibility of the user defined properties using the checkboxes in the drop down window.
