No no text area allows me to enter title

Hello, i could not find the title area when i try to create a new portfolio piece.

i have created my own portfolio in CPT UI and i went to Custom Fields, under Location, i choose "post type is equal to portfolio". However, when i click " add new portfolio pieces", i couldn't see any title area that allows me to type the new name for portfolio piece.

i tried to create another new "portfolio" in CPY UI which called " new portfolio", Then finally i could find the title text area after i clicked the "add new portfolio piece". However, i didn't see the section of featured image even though i already type add_theme_support('post-thumbnails'); in functions.php. Also, the featured image does't show up in the portfolio page.

(here are the information that i entered) in CPT UI Post Type Slug: portfolio Plural Label: portfolio Singular Label: portfolio Pieces Add New: Add portfolio Pieces

Thanks :(.
