'concat' function

Summary:

Concat function is not automatically reacting to changes in the properties?

Content (please ensure you mask any confidential information):

I used the 'concat' function for two resource properties, both of which are text fields. It works well, but when I update either of the two properties, the concatenated field doesn’t update. Is there a way to make it update automatically whenever there is a change in the properties?
