Posts Carousel with Events Calendar

Hi!

I’m currently using the standard Posts Carousel to pull in Calendar Posts from the Events Calendar plugin.

There are several things I’m hoping someone can help explain and help solve.

A. I have it set up so that it pulls in by way of ACF Relationship (I don’t completely understand). Sorting by ACF Relationship was the only way I could get it to sort the posts by date of event and not by date published.

B. Recurring events (Ex. an event is set up for April 1-2) in the calendar posts will show up multiple times on my posts carousel. How do I modify so that I’m only seeing one?

C. At the moment, when a new post is created, I must go in and manually and 1 to the amount of posts shown in the carousel. How do I set it up so that it shows all posts?

Thank you for your time!
