I did read them and wasn't trying to be aggravating, apologies, just wanted to be crystal clear about how it does work for me with the screenshots and all.
This could be something: the mixer and the coffee maker both use the exact same type of blue spot, and I saw you had a mixer in your screenshot; if you pull that off, can you put your coffee maker where it used to be? If so, and if you suddenly couldn't place your mixer somewhere instead, then it may be an issue with something else, like the type of counter.

My mixer now in the other spot:
My coffee maker in its place:
