Issues with dropdown list not displaying right away

Hi all!

We have a dropdown/search block on our site’s Resources page - for easy sorting of content - that is having some issues. When the page loads, it appears as though the dropdown options, when clicked, do not appear right away. Instead, we are only seeing ‘link 1’… and THEN the options display after a few seconds. I tried checking out the various options, but have been unsuccessful in figuring out the issue. Any help is greatly appreciated!
