Missing Google font family in Accordions Plugin

When running a scan of a website with Accordions installed I get the following error:

400: Invalid selector : Missing family name

:wght@100;200;300;400;500;600;700;800;900

This issue occurs in the source of pages of a web site in which Accordions is installed: <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=:wght@100;200;300;400;500;600;700;800;900&display=swap" />

Originating from a call to an empty array in the Accordions /includes/functions.php file

I don't see a way to submit a topic to the forums.  Otherwise I would have submitted it there.
