Players can interpret playlist grouping metadata differently and may combine it with their own sorting rules. The same source can therefore appear as folders in one app and a flat list in another. That layout difference does not automatically mean the account or catalogue changed.
Compare group metadata with local settings
A group-title attribute may supply a category name, but the player can also offer favourites, hidden groups or custom collections. Check whether you are looking at the original source grouping or a local view that you created earlier.
Avoid rebuilding everything at once
Start with one recognisable group and search for a known entry. If the item exists, the issue may be organisation rather than missing content. Review whether alphabetical sorting, category hiding or a favourites-only filter is enabled before importing another copy of the account.
Choose a layout you can maintain
Use a small set of favourite groups for daily viewing while leaving the source catalogue intact. If you switch players, expect to recreate some local organisation unless a compatible export is documented. Do not assume an account login synchronises every interface preference.
