I just found one bug with the post title elementor field. Using the dynamic tags for the post title field will duplicate the custom fields of the other CPT with the current CPT.
Some of the screenshots are for your reference.
The solution of the bug is as below:
I have done some dig with the code and found there is a variable yet to initialize inside the
/wp-content/plugins/mb-elementor-integrator/src/Traits/Post.php file inside the
get_option_groups function the foreach loop defined at line no 30. I just initialize the
$options = array(); at the beginning of the loop and it works as expected.
Waiting for you to make these changes as soon as possible with the next release of the plugin. Otherwise, we need to make these changes ourselves with the code.
