\chronoforms7\chronog3\admin\extensions\chronofc\__shared\behaviors_list.php Line 210 $category not exists

Dear support,
​
I got the error that \chronoforms7\chronog3\admin\extensions\chronofc\__shared\behaviors_list.php Line 210 $category not exists in Wordpress.
​
$category semes to be null or empty.
​
Out of this reson the page faild working with xdebug.
​
I could fixed this with
​

if(isset( $category) &&  $category !=""){

    echo $category;

} 

Update: in Line 118 there is an secound $category missing. I have same code was called.
It seeams to be that the

$category

is missing or a copy arthefact.
​
Because on line 44 stands
​

// foreach($cats as $category => $behaviors){

Best reagarts

thank you!🙂
