Problem with taxonomy fields

I have configured a form with post fields to submit posts on the front end. But the taxonomies fields like Category are showing different fields than what I selected and sometimes it replaces some categories with “Uncategorised”.

Here screenshots showing the field configuration, front end form(while filling the form) and posts list (after publishing):

Also, it just replaces sub-categories with the “uncategorized” category. Can you please check?
