Possible glitch or CSS conflict

Hiya!

I’m having a nasty issue that I’ve narrowed down to either this plugin, or a possible error with my web host. I’m using the Divi theme from Elegant Themes. WordPress, Divi, and WP-Polls are all current. Here’s the issue:

Every few hours to days (it’s a pretty random occurrence) the data following the plugin location (shortcode) bugs out as if part of the plugin is conflicting with something else. The option to vote, including the ‘Vote’ button, disappears entirely, displays the current results of the voting that has been done, and forces a line break before the next module. The glitch (or so I’m calling it) also creates extra space after another unrelated module further down the page above the footer. Could this be conflicting divs?

Here’s a page with some screenshots of the problem: https://oasis.support/poll-plugin-issues/

I created the above page as an example since this happens completely sporadically. I’ve gone through Divi’s CSS to look for conflicting code, but haven’t found anything in particular that would cause it to behave this way. Granted, I may very well have overlooked something.

Please help!
