Expanding more than 7 items

I noticed that on my accordion, for everything past the 7th item, I have to click somewhere in the middle of the title in order to expand the accordion.

Here’s a link to an example:

You’ll notice that for item 8 and greater I have to click somewhere on the middle of the title in order to expand. But for items 1-7 I can click anywhere on the title to expand the content.

Do you know how to fix that?
