Error in creat amplitude with FeynArts and FeynCalc

[HLY-dm]

Dear all,
I use FeynArts to load my own model and creat a 1-3 process:

amp = FCFAConvert[CreateFeynAmp[ins0], IncomingMomenta -> {l},
OutgoingMomenta -> {p, q, k}, UndoChiralSplittings -> True,
ChangeDimension -> 4, List -> False, SMP -> True, Contract -> True]

However the Propagator and Dirac Spinor doesn't look very good in fig1, and I want to get the output just like in fig2, how should I do?

Did you patch the model to be compatible with FeynCalc?

Thanks, it really solved my question!
