I did some googling and found the offending regex code on line 727 of ../testimonials-widget/includes/libraries/aihrus-framework/class-aihrus-settings.php

	public static function validate_terms( $input, $default ) {
		if ( preg_match( '#^(([\w- ]+)(,\s?)?)+$#', $input ) )
			return preg_replace( '#,\s*$#', '', $input );

		return $default;
	}

add a backslash before the -:

		if ( preg_match( '#^(([\w- ]+)(,\s?)?)+$#', $input ) )
		if ( preg_match( '#^(([\w\- ]+)(,\s?)?)+$#', $input ) )

Hope that helps someone!
