In Preferences (on both iOS and MacOS) I have elected to "Show Subtitles". In all items which have URLs, I have used "Reorder Fields" to move the URLs to the top: first field in each item.
In iOS this provides the effect I wished to achieve. To wit, each item appears with its item description, and the URL as its subtitle.
However, in MacOS, I still see the Username being treated as a "subtitle", even though it is not the first field in each (or any) item.
How may I change this behavior in the MacOS version of the app?
