Multiple beautytips are being output

I'm getting an issue where multiple beautytips are being output where there should only be 1.

Here's an example of how it looks in the markup.

<div class="bti-16 beautytips-9 custom beautytips-info beautytips-module-processed" bt-xtitle="" title="" style="background-image: url(https://www.domain.net/misc/message-16-info.png);"></div>
<div class="bti-16 beautytips-9 custom beautytips-info beautytips-module-processed" bt-xtitle="" title="" style="background-image: url(https://www.domain.net/misc/message-16-info.png);"></div>
