Strange text in the front end: “<abbr class="wpgdprc-required"

Hello,

I’m using OceanWP theme.
All plug-ins are updated.
In the archive pages, I have this text:

<abbr class=”wpgdprc-required” title=”Devi accettare questo checkbox.”>*</abbr>

NOTE: replace “0” with “o”.

Is it a bug of Cookie Notice & Compliance for GDPR / CCPA or what? Thank you.
