Undefined Variable responsive_view_320

Hi,

I’m using the free version off “Advanced Floating Content Plugin”.
My PHPLog shows the following errors:

Undefined variable: responsive_view_480 in D:\WampDeveloper\Websites\www.xxxxx.dev\webroot\cms\wp-content\plugins\advanced-floating-content-lite\public\class-advanced-floating-content-public.php on line 136

On my homepage the following errors are displayed:

Notice: Undefined variable: responsive_view_320 in D:\WampDeveloper\Websites\www.xxxxx.dev\webroot\cms\wp-content\plugins\advanced-floating-content-lite\public\class-advanced-floating-content-public.php on line 205

Any Ideas what would be causing this?
