Siteorigin Button will not load on Edit

You can see the Widget area but not the button components, you just get the loading animation. If you create a new Siteorigin Button it can also not be seen while in Edit mode. When you save the page then try to edit the Siteorigin Button, it still shows the loading animation. Created yet another Siteorigin Button within another column and it works.
