I see.

Yeah, I've seen the same in my setup, so I will report a bug for cmake
upstream.

Okay, now I've found them, the interface is a bit irritating though,
because when opening the reproducible builds page amd64 is the default,
and it eluded me that when clicking on one of the i386 builds the
details in the pane above change. It would probably be better  to have
the archs first listed and the according (changing) details below.
