original listed under arrangement

[k_b]

I transcribed an original composition and uploaded it as being the arranger, but I am not. I am the transcriber. Now the piece is listed under arrangements, when it should be listed under originals.
How can one fix this?

You need to upload as editor in such cases.

Thank you Carolus.
How can I fix this afterwards?

Use the "Add your own edition" option when uploading and logged in for new things. For items added previously you need to use the edit window and amend the {{LinkArr|Firstname|Lastname}} template to the nearly identical one for editor {{LinkEd|Firstname|Lastname}}.
