I don't understand "Contact person" on top of Transactions record

Hi,
when we add a contact person in a transactions record (not sure the name of the field in english because the title of this section doesn't translate but it's something like "other contact"), these is a new "Contact person" section that appear on top of the record.

Can I not show this?
Or at least also show the main contact of this record inside this box?


thanks
