Studiomux finally opens in iOS 14 but no effects

Have not been able to use Studiomux since iOS 14 came out. It used to work perfectly with Logic Pro till then. Today I updated to iOS 14.4 and Studiomux opens again but when I go and try to add effects or instruments it only shows miRack and Model 15. I need to use Flux again like I used to and it’s not showing up. Any idea why?
