make some change on "Listing Submit"

Hello everyone

I want to make some changes to the “submit listing”

1- change some titles to Spanish (photo attached)
2- remove some parts.

(Photo attached)


use “Loco Translate” and it worked but not for everything, some texts were in English and my target audience speaks and writes Spanish of preference.

How do I make these two changes that I want to make? or who advise me?

I’m something new in wordpress, I’m in the process of self-learning

You can see my page, I think I’m fine.
