When I type 'calc' I get the calculator as the first entry in GNOME.

Even after I move over and opened LibreOffice Calc, subsequent searches still gave me the calculator as the first entry.

I'm not exactly sure how it works, but I don't seem to have the same issue that's being mentioned.

It does, but it has a short memory. If you select Office by accident, it'll then start showing that first again for awhile.

It wasn't doing it before, but I have a new System76 machine with a fresh GNOME install, so let's see if it works here.

It does, it can just be overridden easily.

It does for me.
