I discovered while building a site that toolset blocks for image, audio and views at times fail to show settings. After some playing around I discovered this happens when the field is not populated.
I created hidden link to verify the problems occur with a minimal wordpress site, only toolset blocks have been added.
To recreate the problem I
Created a new content type.
Add fields for the content type, including image and audio fields.
I then created a content template for the new type.
When adding either an image or audio toolset block the settings do not show.
Adding a "Single Field" block seems to work.
Adding a instance of the content type without the fields populated and then editing the template did not resolve the issue.
After adding an image to content and then editing the template, selecting the image block now shows the settings. (Note the image does display even without editing the template)
It would be nice is the settings show even if the field is not populated, if not practical, it would be nice if the block interface when it can not display the settings, display a message instead of nothing.
It would also be handy if it was possible to search for content to "View with", instead of being limited to those in the dropdown.
Thanks
