Groove Agent Missing VSTSound files

Has Steinberg recently renamed a load of their VSTSound files? I’m seeing hundreds of duplicate, paired instruments in the Instruments tab, one of which is correct and the other missing (with the Red “Stop” symbol). For example, the Instrument “Eruption - Bass” is fine under the reference 956A11AEA67746B0BD4… (there’s more, I got bored typing), but is missing under the file reference 1F727E23977A44BBAA… and so on. It’s as if they’ve renamed many of their VSTSound files and forgot to tell Groove Agent.

Do you know about the Steinberg Library Manager?
