GFCI Outlet Issues

I have two hot outlets in my kitchen, on two separate breakers but one trips the other. I put a GFCI on the one that trips them all and all the outlets work, but when I plugged in my refrigerator it blew the GFCI. Does this need a 20 am GFCI? I had two GFCIs one on the secondary hot outlet and one on a load outlet going the other direction and everything worked. When I put the GFCI on the one that is hot and trips the second one, everything shorted out.
