“Display None” in Code of Site

When I went to create a new post, I noticed the sliders are no longer showing in my posts. Essentially, it’s showing up as display none in the code of my site. I recently changed my theme and updated the version of WordPress so I’m not sure if either are causing the issue. I tried deleting and reinstalling Meta Slider but that did not work. I do not want to change my theme and would like to continue to use Meta Slider so is there anything else that can be done?
