The attributes plugin doesn't show the personal users only

When adding a field so that only the author can see it, it doesn't work. If you enable "Add to item" with these settings, all users see this field, even those who aren't registered.
Please correct this error

Personal users = users those are not companies (company set to 0 in user account)

The old version of the plugin works, but the latest version doesn't.
If the user's company status is set and the display for company users still doesn't work
I didn't understand where to set the value to 0

How can I make the phone number field visible only to the author of the publication?

Wrap it to
<?php if(osc_is_web_user_logged_in() && osc_logged_user_id() == osc_item_user_id()) { ?>
....
<?php } ?>
