Older kernels (< 6.0) not showing

I'm trying to install a 5.18.X kernel, however only >6.0 are showing in mainline list.

I'm on ubuntu 22.04.3

In the gtk gui, I had inserted "-1" for "Show prior major versions" in settings, however it appears that isn't honoring this setting. Once setting this to 99, I was able to see more versions.

--previous-majors all in the cmdline works as expected
