Because FeynCalc and FeynArts are not writed by the same author, there are always some incompitable problems. So the best way to use them is: firstly only use FeynArts to generate amplitude and save them; then quit kernel, and only install FeynCalc to handle the amplitude.
Note: if one only install FeynArts, one should use FullForm (StandardForm doesn’t work) to see the actual expression of amplitude.
