Membership 2 Pro & LayerSlider conflict (layerslider won't save

I have tested this out and found out that LayerSlider will not save slide changes when Membership 2 Pro plugin is active (after I deactivate this LayerSlider saves like normal).

Here is the error in the backend: Uncaught TypeError: Cannot read property 'substr' of undefined (in admin.js within LayerSlider Plugin).

Line 1739 : if(jQuery(this).attr('name').substr(-2, 2) == '[]') {

Any suggestions?
