I'm not exactly the cause of the issue but it could be theme related as this is not the first i've seen this issue.
I've seen it in the past and its that sometimes the theme will set the view div area to visibility: hidden;
How I knew it was hidden was because I used the Chrome page inspector to view the html and css that is being loaded on the page. Take a look at the screenshot
I cannot give a that has 0 issues with Toolset because our plugins are a constant work on improvements and adding new features.
Features which may cause issues in other theme and then the theme might update and causes issues in our plugins. So its not possible to recommend a theme like that.
Today everything might be ok and then tomorrow an update is pushed that may cause conflicts.
