The [subscriptionform] shortcode is affecting my mobile navigation

Hello,

I'm working on a website that has both a desktop and mobile layout. I've noticed that on the mobile version, my menu toggle button doesn't open whenever I'm on the registration page. It's clickable, but doesn't toggle open the mobile menu. I further tested it by removing the [subscriptionform] shortcode from the page, and once I refreshed it the mobile navigation opened fine. When I put the shortcode back in, the menu stopped working.

I was just wondering if you've heard of anyone else encountering this issue and if you have a suggestion on how to solve it. I googled it and searched the forums and was unable to find anything on it. Thank you!
