Anyone have any new information on this? I am experiencing this with some Custom Properties and not others
For anyone experiencing this problem, I was able to resolve it by turning off all Orion Services in the service manager and turning them back on. Once I did that, the Custom property field was correctly rendered.
I assume this is a bug with the Orion system because I don't feel you should have to shutdown the system to get it to recognize a new custom property when using a variable.
