Getting quote character in title

Hi! I have noticed a problem with the accordion shortcode whereby some entries are not showing the correct title. In fact, the title starts with a quote and is truncated after the first word. Here is a test page that shows the issue:

I have the same entry in the first and the last position and it does the same thing in both places. I removed the openfirst and set it to close, still a problem. I even changed the title to something else, and nothing helps.

Here is the code:

[accordion openfirst="true" clicktoclose="true"][accordion-item title="This is the first element" state="closed"]
