Hey no worries, we can see that it is a mistake and that you are trying to post only one time
The mistake is easy to fix
There is an EDIT button
next time you could always just add the missing info into your post by editing it, and having only one post

but now that you have 3 posts, EDIT two of them, delete everything inside and just write the word Mistake, Don't Upvote in both the TITLE section and the writing text section and leave it at that.

Ok sir. Thanks a lot. I will try to do that as soon as possible.

I think I am still having challenges with editing those posts. This screenshot below is what I see when I click on "EDIT".
