Thanks for your help.
I cleared the cache at the Breeze plugin by changing Purge cache after to 1 minute. Waited then set it to 1440 again.
Then I changed “Load using Ajax” to Yes. I did this for only one poll.
The result: that poll disappeared from the page except for the top, horizontal line of the box. You can see it here https://solotravelerworld.com/solo-traveler-showdown-best-nature-destinations/#. It should be the first poll after “Here are today’s four polls”
