I agree, the plant is incorrectly tagged, which happens quite often at garden centers when customers take a label out to read it and then go to put it back and it ends up in the wrong pot.
It's definitely not Peperomia 'Hope' and I'm not all that familiar with succulents but I'm not sure it's Portulacaria afra either; the stems look more like Crassula to me. Hopefully one of our more knowledgeable members who grows succulents will be along with suggestions.
