Some issues, unable to switch results page

In the survey in the multi-tab, except for the first survey, you can switch to the results page, and the latter will not work.
The survey in the pop-up mimic box cannot be switched to the results page.

I like your plugin and hope that the author can fix it as soon as possible and update it, Or provide access to resolve.
