div.slick-slide aria values

I have been tasked with getting our main website up to WCAG Accessibility standards so that we can have an audit run but before that, I am trying to be proactive and locate issues beforehand and get them correct. I used the chrome Dev Tool -> Audit and I received the following errors when it comes to the slider at the footer of the page.

[aria-*] attributes do not have valid values
Assistive technologies, like screen readers, can’t interpret ARIA attributes with invalid values. Learn more.

I have scoured through WordPress and I am unable to locate where the edits need to be made and once located what edits need to be made. I am pretty new to WordPress but have made edits elsewhere just unable to locate the issue here.

Please let me know if you have any questions.
Thanks,
