A 4.1(a) finding on your own brand usually means the reviewer can't connect the App Store account to the "Erendor Online" name. Play Console screenshots don't prove that to Apple, because Google accounts aren't something they can verify. What tends to work:
Proof Apple can check: a trademark registration or filing in the account holder's name, and/or an official website on a domain you control. The site should name the developer exactly as it appears on the App Store and link to both store listings.
Upload that proof as an attachment in your App Store Connect reply (and in the App Review Board appeal), not only as text. Keep the message short: who you are, the proof, and one line confirming no other developer is involved.
Since the metadata didn't change, look at what's new inside 1.1.27 compared with 1.1.24: new art or logos, a link to a fan wiki or Discord, server or community names. One of those is often what the reviewer matched against "third-party content".
On the Extended Review flag: there's no way to request its removal directly. It usually drops off after a clean approval, so it's worth getting the ownership proof right before the next resubmission rather than resubmitting repeatedly.
