I have a project That I have recently upgraded from 2015 -> 2018->2022 in which I have some custom properties defined. I usually use those the filter the string lists using a basic expression. In this project the filter is not working. I can access the properties from the visual basic editor as expected.

Creating similar properties in a new project appears to work as expected.
Adding new properties to the converted project does not work.
The filter functions as expected in the base 2015 project

I suspect this may be due in some way to the conversion process. Any ideas on how to get the user defined properties in the converted program to work ?

I can provide the project (or a cut down version of it ) on request
