When LayerSlider Warning: array_merge(): Argument #2

In my frontpage I have a Slider with dexp_layerslider version 7.x-1.0-beta

And outputs this warnings:

Warning: array_merge(): Argument #2 is not an array a ctools_process() (línia 763 de /.../www/profiles/drupalexp_organicfood/modules/contrib/ctools/ctools.module).
Warning: array_unique() expects parameter 1 to be array, null given a ctools_process() (línia 763 de /.../www/profiles/drupalexp_organicfood/modules/contrib/ctools/ctools.module).

What can I do ?

Hi.

The param here is the content ID that you want to filter. you can add id list as id1/id2... ie. 1/2/3
