github-pages-with-jekyll #7

Hello! I see that it’s not only me with problems in subejct 7 of github pages. I have tried everything and problem persists. The bot corrector says I didn’t include correctly the tittle, but I’ve done everything what is needed. Could someone help me please? I’ve already checked spaces, spelling, _posts file, etc. Here it’s my code:

Is this a question in regard to the GitHub Learning Lab Pages course?
