Causes other widgets to disappear

Two widget areas on my page kept disappearing after refreshing the browser in Chrome on PC and all browsers on Mac. After hours of trouble shooting i finally narrowed it down to this plugin. As soon as I deactivated everything worked fine. The two widget areas that were disappearing were the only two after this plugin in the document flow. So it seems it cancels anything after it in the flow.
