Hi,

Thanks!

It also happens with Tarcer in Feyncalc 9 running with mathematica 10.4.

Try

TarcerRecurse[+TFI[d,P^2,{0,0,1,3,0},{{2,0},{1,0},{0,0},{0,0},{1,0}}]].
The out put is (2 P^2 Subsuperscript[F, {Tarcer`Private`n1,Tarcer`Private`m1}{Tarcer`Private`n2,Tarcer`Private`m2}{0,0}{0,0}{1,0}, (d) 01110])/(d+2).

Best,
Yan
