Actually, you can’t uninstall it by default because it’s a “system” package, so run this SQL:

UPDATE Packages 
SET IsSystemPackage = 0
WHERE PackageID = (SELECT TOP 1 PackageID FROM JavaScriptLibraries WHERE LibraryName = 'Selectize' ORDER BY Version)

Then clear the cache (in Servers page of Persona Bar). Finally, you can now uninstall the library via Extensions

Ha, then yeah, something is not normal there having 9.4.1 persona bar on 9.3.2 dnn… 😃
