Hello Team,
I have two copies of a custom fields (name - Aha! Reference) of type URL.
I need to figure out which one of the below two custom fields is obsolete and which one is actively used.
I am unable to search if this field is empty or not as it is of type URL. Also the last used say "no info" for one of the fields. Does that mean it is not actively used ? Could someone help me to determine the usage of these fields ?

Thank you!
