What _I_ mean is that these two rolldown widgets have different purposes. I do
use the one you mention, as an answer to the question "Which version of the
software has a problem?". The other one ("OS") answers a different question:
"On what OS were you running that software?" Among the possible OSes, I see
various NetWare, Novell, but also Windows operating systems; among SUSE and
openSUSE OSes, I see "openSUSE Factory" but not "openSUSE Tumbleweed", I see
openSUSE versions up to and including 42.3 but not further, and I see "SUSE
Other" which I suppose is a catch-all for any SUSE or openSUSE OS not included
in the list. Since "openSUSE 15.1" and "openSUSE Leap 15.1" are not mentioned
in that OS list (which, I repeat, includes various Windows OSes, and Factory
but not Tumbleweed) I turn that "OS" rolldown widget to "SUSE Other" when I
report a bug, because that's what comes closest to the OS I'm actually running.
At the same time, I also turn the Version widget to Leap 15.1. See fot instance
bug 1160487 as a recent bug I reported.
