When you are in the Registrant tab of a FAF event you have the ability to enter in filter fields, such as first name, last name, etc. If you enter in a search filter for one event and then go to a different event that filter that you filled in is still populated. This can be confusing for users and it would be better if the filters cleared everytime you went to a new record. I have seen this for FAF filters as well as custom filters that I added to data lists.
