The WordPress <!-- more --> tag only works on archive pages, e.g. the blog page, so that only a part of the post is shown when viewing a list of posts, it isn't intended to work on individual posts or pages, where the full content is shown.
You want that the post content is partly hidden even when a user visits the individual post?
That's not something that is supported by WordPress or Toolset, you will need a custom solution for that.
Sorry, but debugging custom code is outside our support policy. It is not an issue that is particular to Toolset so you could ask for help at Stack Overflow (wordpress.stackexchange.com).
I visited your linked page and checked the browser console it seems you have a syntax error in your code from an unexpected '<', so before anything else I would carefully read over your code and see if you can spot the error.
