When you click on any other "Deal Name"s you will find contact persons with email addresses. Maybe the can support or have contacts who can support ?
I would do this by my own and would ask them, but I have to less financial knowledge unfortunately and I haven't followed this ISIN / CUSIP discovery.
There are so many rumors and speculations and time goes on and on .. Maybe some expert/s at usbank can support or know somebody who can support ? Why not try if they maybe have more information than we have ?
