Leap 15.0 wants to update to Tumbleweed?

Hey, I’m relatively new to OpenSuse and a ran into the same Problem already twice, and I didn’t find any solution for it so far online.
.
I tried to install KBibTex through https://software.opensuse.org/ (and I did not check for which distro is was supposed) and while installing there was a conflict, which I tried to avoid by choosing “Ignore Dependencies”. After the installation was finished, it did not work (kind of what I expected) I uninstalled it and I thought I was done.

But now to my Problem. When I’m trying to run zypper update, it seems like it wants to upgrade my distro to Tumbleweed. I get this output:

The first time, this occurred I just installed the factory image over it, but I’m not very keen on doing this every time. Thanks for the help!

What repositories have you enabled

sudo zypper lr -d
