Please note that we have blocked price tiers that don't fit the number of tracks of your release: your release's price must be inferior to the sum of the price of all the individual tracks. However, if you wish to choose a different price for your release, you may indicate it to your Label Manager, who will be able to modify it. For single track releases, the release price will always be the track price.
You may also have created several volumes instead of multiple tracks in your release. If this is the case, the system will not be able to propose a price tier for your release. Go the "Edit assets" tab to make sure that you haven't created multiple volumes. If you have, you may click on "Move to another volume" (at the right end of each track) and slide the track into the first volume.
