Crashing when building out view.

I downloaded the module and installed. Now if I go to a create a new view I get all the way through the process but when I click on settings for mixitup the loader spins like it is thinking the goes away without showing the settings page. From there if I click on the mixitup part in the view I get a page that shows white with lots of text in it. Here is a small sample of it. I can provide more if needed.

[{"command":"settings","settings":{"basePath":"\/","pathPrefix":"","ajaxPageState":{"theme":"seven","theme_token":"CshUgJxK-YSyuqghjXEhTRpVFP6bq-Nzo6ez6usSXZA","jquery_version":"default"},"autologout":{"timeout":4999999500,"timeout_padding":10000,"message":"Your session is about to expire. Do you want to reset it?","redirect_url":"\/user\/login?destination=admin\/structure\/views\/ajax\/display\/portfolio_items\/page\/style_plugin\u0026autologout_timeout=1","title":"BookFuel Alert","refresh_only":true,"no_dialog":0},"urlIsAjaxTrusted":{"\/admin\/structure\/views\/ajax\/display\/portfolio_items\/page\/style_plugin":true}},"merge":true},{"command":"viewsDismissForm"},{"command":"viewsShowButtons","changed":true},{"command":"viewsTriggerPreview"},

When looking at my watchdog errors I see these.

Notice: Undefined index: use_sort in views_plugin_style_mixitup_views->options_form() (line 116 of /Users/mikewalcott/Documents/Develop/wavecloud.com/sites/bookfuel/modules/contrib/mixitup_views/views_plugin_style_mixitup_views.inc).

Has anyone seen anything like this. I have also downgraded the module and tried all version with the same result. I have spent 2 days on this and am driving myself crazy. Any help would be much appreciated
