 * After an update to the latest version (around 15-Apr-24), there is a PHP Warning:
   Array to string conversion in “includes/acf-value-functions.php” on lines 96 
   and 122 which are:
 *     ```wp-block-code
       96: if ( $store->has( "$post_id:$field_name" ) ) {
   
       122: $store->set( "$post_id:$field_name", $value );
       ```
   
 * I tried to log the “$store” which is the following:
 *     ```wp-block-code
       ACF_Data Object
       (
           [cid] => acf-6
           [data] => Array
               (
                   [8963:banner_image] => 
                   [8963:banner_image:formatted] => 
                   [9231:banner_image] => 
                   [9231:banner_image:formatted] => 
                   [9270:banner_image] => 
                   [9270:banner_image:formatted] => 
                   [14473:banner_image] => 
                   [14473:banner_image:formatted] => 
                   [9013:banner_image] => 
                   [9013:banner_image:formatted] => 
                   [14481:banner_image] => 
                   [14481:banner_image:formatted] => 
                   [9279:banner_image] => 
                   [9279:banner_image:formatted] => 
                   [15541:banner_image] => 
                   [15541:banner_image:formatted] => 
                   [1:banner_image] => 
                   [22:banner_image] => 
               )
   
           [aliases] => Array
               (
               )
   
           [multisite] => 1
       )
       ```
   
 * I have not changed the fields. Any ideas? Thank you.
