How can I uncheck an item previously selected in the Gift Registry Widget?

We are using the gift registry widget for user to select a song, some users have mistakenly selected a song, and now want to change it, so can you tell me how to release a song and make it available once more ?

For Eg, you can look at releasing #2

I'm afraid there's no way to release or remove the assigned submission to an entry on your Gift Registry Widget. Sadly, the only way around this is to delete the particular submission associated with the selected song to free up the slot again and make it available.

Below is an example of how it would work. On the short GIF animation, I have the form showing with 2 songs already selected (both are showing NONE left). I then went to the Submissions Page and deleted the previous submission associated with it and after reloading the form, the selections were available again.

IMPORTANT: Deleting a submission is irreversible and can not be undone.
