losst stylesheets

I really like this plugin and work a lot with. But since I’ve upgraded to WordPress 4.0 the stylesheets are no longer visible. The program still work, you can add a new sheet but after saving you can’t see it in the register so it is not possible to correct or delete any style. Any idea how to fix it? Thnx in advance
