Precision SKUs missing from Latest catalog in Repo manager

Hi, I need to create a firmware update ISO for my R7910, but the Precision line seems to have disappeared from the enterprise catalog, along with the Powervault line. When I first downloaded the program, I saw the catalog was from late 2019, and it had both the R7910 and R7920 available under the "precision" product line. Trying to create the repo, however, lead to an infinite loading wheel. 

Now that the catalog has updated to the new 20.03.01 catalog, all precision and powervault machines are gone, and I cannot create an ISO for my machine that is still supported. How can I obtain a bootable ISO for my R7910? All the box links are dead and the new site only has Poweredge ISOs.
