Sharepoint Websitename cannot be changed in Admincenter

Dear all,

we copied a website template from Microsofts' lookbook which was named "Hybrid Work" and changed it to or needs. However, we are not able to change the website name. If I change the name in the administration center, Sharepoint gives a success message. But after reloading the page, it is named "Hybrid Work" again. This behavior keeps persistent for a week now. I can change every other website I have access to but not this one. We only see it in the Overview on the "News from sites" page, but it is quite annoying.

Does anyone know this behavior? Is there a workaround for this?

Thanks in advance,

Jacqueline
