I checked on a local test site and when generating the access shortcode I checked the option to "Display the text without any formatting" because... why not?... and everything appeared to work correctly.
So I removed the raw="true" attribute which that added to the toolset_access shortcode and then the WYSIWYG field failed to display, so that appears to be the problem in your case.
Please add the attribute raw="true" to your toolset_access shortcode and test again, I expect that will work.
