Looks like this Release was added without selecting the proper recordings.
This release is just a box set that includes: Double Live and Triple Live. What is the easiest way to merge the recordings with the proper Recording?
Use this script and merge the recordings from the Double Live & Triple Live with the recordings here.
Yes indeed, this script was exactly done for this case.
There is some help and support topic over there:
I have finally merged recordings and added medium titles for Double Live (it was already the case for Triple Live).
I have also linked Double Live and Triple Live release groups to [That] Anthology release group.
