A ManiaPlanet (or TM2020) item has a name attribute (different from the file name) that ItemExchange uses for the item display name. Unfortunately, I don't think I can change this attribute from within ManiaPlanet. A set of items I uploaded recently has been affected by this issue. Most items in that set have the name of an old item of mine (SplashPlatformBlueFull) that I based my current work on.

In an attempted workaround, I tried changing the name of each affected item on ItemExchange, but those name changes are not reflected within the set tree. I was thinking of hiding my current set and creating a custom set from the renamed items, but I would appreciate seering individual item name changes reflected in the set tree, or I could edit item names in the set on ItemExchange.

EDIT: The names are now correct in the set tree.
