I suppose you are using FeynCalc 8.2, since there your example indeed fails.

Well, what can I say: FeynCalc 8.2 is like Internet Explorer 6, outdated
and full of bugs, but for some reason people still stick to it.

It would be easier if you could say why your code does not work with FeynCalc 9.2. In 99% of cases this is something very easy to fix by changing a few lines. Moreover, I’m all in favor of adding compatibility options to make old codes work with the newest FeynCalc versions.

If you prefer to use the version 8.2, then I’m afraid that I can’t help you: The bugs that you report are there, but they have already been fixed in the newer FeynCalc versions.
