Adding GitHub to Jira

[Leon Rensch]

Hello dear community,

I want to add our GitHub repository to Jira for our project.

The problem is, in my first attempt I added a repository from my own GitHub account to test the function. Now I tried to add the actual one and it doesn't work.

I am not able to successfully connect the new one.
There is a list called "Connect a GitHub organization to your Jira site" in which my test repository and the actual one are shown, but I can't remove either.

I am not able to delete the "test" one because it says:
"This organization hasn't been connected yet. Cannot delete this subscription."

I am not able to delete the actual one because it says:
"You must have admin permissions to delete Jira subscriptions. Please contact your admin."

And if I want to connect the actual one at least it tells me:
"You need repository admin permissions to install this app. Please contact your admin."

I am the creator (so I guess I am also admin) and the creator of the repository is a project member. He logged into his GitHub on my Jira to link it.

If you can help me, it would be very helpful so thank you.
