Hi there,
I have been where you are at. Coming from a full stack development, it was so easy to debug and trace variables. I too sometimes find it extremely frustrated at the lack to being able to track certain things.
An alternative way when I hit this wall is find all the possible BR, UI policy, etc that could possible change the value. My go to is a code search. You can go to:
/sys_metadata_list.do/?sysparm_query=&sysparm_view=
in your instance and do the "for text" search for the variable that is being changed. This way, you can start to pin point where and maybe when something is triggering to cause that change.
Hope this helps.
