CSS set to display:none when not logged in?

Hi there, thank you so much for creating an amazing plugin!

I had set up a website at the start of January with an RSVP page. The website is hosted on siteground, with Elementor installed and the Astra theme used. I had created a dedicated page and inserted the shortcode [rsvp] and had no issues with the plugin when it was first set up.

I then hadn’t revisited the website in around 1 month so had made no changes but automatic updates of the plugins (Elementor)/themes (Astra)/wordpress (latest version) have taken place since then in the background.

When viewing the RSVP page today, only the title was showing and the RSVP area was not visible at all (seemingly similar to the previous post on the support forum?). I tried several browsers, tried clearing all local and server caches, but the only way the RSVP area would be visible was if I was logged in as an admin on the website.

I inspected the page and noted the following CSS was present:

.rsvpArea, .rsvpParagraph, #rsvpPlugin {
display: none;
}

I have now added custom CSS to change this to display: block; and this has resolved the issue, but it feels like a bit of a patchwork fix? I was just wondering if anyone could suggest why this has happened? I have no other custom CSS and no other plugins installed other than Elementor.

With the CSS above I technically now have no significant issue but I thought I would still post in case anyone else is having the same issue or a fix is needed?

Thank you advance and thank you very much again for a great plugin.
