Dashboard can't get submitted custom posts stored in custom table

Hi, i just reset the site for testing the plugin MetaBox Frontend Submission.
This time, i did not use the custom table and wrote any code, but the dashboard still can not get the submitted custom posts.

The shortcode used in frontend submission page: [mb_frontend_form id='diet_form' edit='true' allow_delete='true']
The shortcode used in frontend dashboard page: [mb_frontend_dashboard edit_page="14"]

The screenshots of the frontend dashboard page, frontend submit page, wp_post in db and wp_post_meta in db is shared by google drive: https://drive.google.com/drive/folders/1qGVuJ34otr1vkLspoCMsXBUspZurOs1M?usp=sharing

In the wp_post_meta, you can see post_id with 26 and 31 is the newest custom posts submitted by user with id=2. In the dashboard page, it shows 0 post for that user.

Hi, the dashboard works and can show the submitted custom posts. However, the post counts still be zero, i.e. still show "You have 0 posts".
