Access Levels shows open h2 header tag instead of Button

I've been trying the Membership plugin, and when I go to the access levels page, I'm not seeing the "add level" button, but rather something that has an unclosed H2 tag.

I've taken a screenshot and posted it here:

Please let me know how to correct the code.
