Unparsable structured data issue detected

When I use the content toggle blocks and turn on FAQ schema I get an error on the website and in search console.

Here is the error on the website when FAQ is turned on (near top):

Warning: array_unique() expects parameter 1 to be array, null given in /home/customer/www/rockfordpersonalinjuryattorney.com/public_html/wp-content/plugins/ultimate-blocks/src/blocks/content-toggle/block.php on line 110

Warning: array_values() expects parameter 1 to be array, null given in /home/customer/www/rockfordpersonalinjuryattorney.com/public_html/wp-content/plugins/ultimate-blocks/src/blocks/content-toggle/block.php on line 110

Here is the highlighted part in GSC error:

l]}</script><script type=’text/javascript’> /* <![CDATA[ */

Full entry:

“mainEntity”: [ul]}</script><script type=’text/javascript’> /* <![CDATA[ */
var wpforms_settings =

When FAQ is turned off it goes away.

By the way – this is only on a single page of the site. I use this same content toggle on other pages with no issues. Here’s an example – https://www.rockfordpersonalinjuryattorney.com/car-accident-lawyer/
