Did all the steps?
To create the ref type, you went into endnote preferences first to create and name the fields in the Endnote program. - What did you start with? one of those named “unused”? or modified the Audiovisual or Film ones? Then you gave it an appropriate name. (by the way, this is only on the machine you do this on, if you use other computers/laptops, you will need to download and upload the ref type table to the other computers with Endnote desktop programs.)
Then you opened your preferred output style and created the bibliography template for that ref type which should appear in the drop-down and remember to “save as” to a new name.
Then you need to change the output style in your manuscript on the Word Endnote ribbon, to the newly named output style.
You also need to remember to change your photograph record to be that ref type in endnote.
