tabindex and skip links issue

Hi,
when using lighthouse I see two issues appear with the plugin.
One is: Skip links are not focusable

Including a skip link can help users skip to the main content to save time.

a#pojo-a11y-skip-content.pojo-skip-link.pojo-skip-content

Second is:
Some elements have a [tabindex] value greater than 0
Failing Elements

a#pojo-a11y-skip-content.pojo-skip-link.pojo-skip-content

Is there a way to fix this? Thanks in advance.
