fusion slider broken

Hi auto optimize team,

unfortunately I would like to delete the auto optimizer plugin, but if I do, it breaks the fusion slider of the Avada theme. It is a problem with the Javascript optimization, the merging of Javascript files (second option from top) more specifically. If I reinstall the plugin and recheck the option the slider works again.

How can I roll-back the merged JS-files option safely, without distroying the slider? I tried activating the JS-compiler of the Avada theme, but not difference.

Thanks a lot for your help, much appreciated.
