Unable to suggest a score be added to a "song".

"What You Need" is a song. https://musescore.com/song/what_you_need-2771246/sheetmusic

This is my transcription of it: https://musescore.com/user/27997005/scores/7570214
This is someone else's transcription of it: https://musescore.com/user/26783683/scores/7102500

For some reason, I am unable to suggest that their transcription be added to "song" 2771246. Mine is, though.
