This is really about the colour picker, and which one you are using,
not about CMYK. It's doing this for me too, although i'm not sure why.

But to work with CMYK you might want to consider using separate+, or
working with Krita, which supports CMYK images directly (and i imagine
can export as a CMYK tiff although i don't know for sure).

You are editing an RGB image in GIMP, not a CMYK one. it doesn't matter
which colour picker you use, you'll get an RGB colour.

Converting colours from RGB to CMYK for print can be done in multiple
ways (e.g. with undercolour removal to save ink).

I agree the colour selector is misbehaving, though.
