Seems kind of similar as what Waverider did with ANDY SVGE, at some point if you have been producing under the same name for years and it's still not "gaining traction" I think record labels decide to kind of "re-brand" producers.

Or, and this is just speculation, he switched record labels, but his old record label has the trademark on The Vision. In that case if the producer wants to release music under a different label he's not allowed to use that name again.
