Well, I wouldn’t call it a bug…
FeynCalcExternal translates
Eps[LorentzIndex[l1],…,Momentum[p1],…] into
LC[l1,…][p1,…].
For this to make sense, the arguments to Eps must be a list of Lorentz
indices followed by alist of momenta, not vice versa and not mixed. This
can be achieved e.g. with Calc.
All in all, a matter of notation.
