Cannot change or save Snippet Title

I was having trouble saving the title of my snippets, but the snippet itself saves fine but with an “Untitled #X”. I also cannot change the title of existing snippets. Trying to type something in the title field deletes everything and then the plugin thinks I am trying to save without a title. In new snippets that I create, I cannot even type anything in the title field.

I’m using the latest version and I have already deactivated all other plugins and changed back to a default theme to rule out any conflict in that regard.
