Default param not showing on user macros

How to recreate:
1. create a new user macro
2. add an enum type param, define at least 2 values and choose one as a default value
3. print the param to the screen
4. create a new page and call the macro
5. in the macro options toggle between the param default value to the other values and you will notice that when choosing the default, the name of the param appears instead of its value
