Compatibility Issue with Custom Sidebars – Dynamic Widget Area Manager

Hi,
there seems to be some some compatibility issue between your plugin and Custom Sidebars – Dynamic Widget Area Manager (https://www.ads-software.com/plugins/custom-sidebars/). When I try to modify custom sidebars unter Appearance > Widgets, I end up getting a javascript error. Once I deactivate your plugin, it works.
I have described the error in the other plugins support forum (https://www.ads-software.com/support/topic/javascript-error-in-admin-area/)

Thank you
