There is a new starting page for our servicedesk portal which should not be there

For some reason our service desk portal has an extra page in front of it. I have no idea where it is from. It looks like a confluence article a colleague made but I cannot find it anymore. 

How can I remove it?

The wrong page:

The correct page but with /group/-1 added to the url:

Hey Martijn

Zou het kunnen dat je een extra group hebt aangemaakt bij je request types?

I noticed I didn't answer yet,  but the first screenshot seems to be from an other Jira project as your screenshot in your answer.

Is it possible that you have 2 Jira service Desk projects or more? 

And that what you see is comming from one of those other projects?
