Hi,
If you have several meta boxes and display on one user profile page, please use the attribute id
with meta box ids and commas instead of using more shortcodes on one page.
Current case:
[mb_user_profile_info id="meta-box-id1" submit_button="Submit" confirmation="Your information has been successfully submitted. Thank you."]
[mb_user_profile_info id="meta-box-id2" submit_button="Submit" confirmation="Your information has been successfully submitted. Thank you."]
Recommend:
[mb_user_profile_info id="meta-box-id1, meta-box-id2" submit_button="Submit" confirmation="Your information has been successfully submitted. Thank you."]
For more information, please follow this documentation https://docs.metabox.io/extensions/mb-user-profile/#edit-profile-form.
