Ok it looks right except you have it set to open by clicking on the titles and to show the select button. Both of these are settings that can be changed on the admin section of the plugin. There is a config called 'use titlebar as button'
The button called 'select' is just a helper to select the contents of the spoiler, not to open it. You can turn that one off and turn on the 'open/close' button (or have both).
My guess is trying to get things to work you ended up in that config.
You want to do this:
uncheck 'use titlebar as button'
and (if you do not want the select button) uncheck 'Show select content button'
Then click on 'save settings' at the bottom
let me know if this works
