Abstract
In computing the two-loop QCD corrections to a class of Feynman diagrams for the process $q\overline{q} \rightarrow ZH$ in Higgs effective field theory, we discover a striking phenomenon. We find the need for an additional local composite operator in the renormalised Lagrangian while employing a non-anticommuting $\gamma_5$ in dimensional regularisation. The computation using anticommuting $\gamma_5$, however, does not require any such amendment.

Report
This is a contribution to the proceedings of the RADCOR/LoopFest 2021 conference. It will be published as a SciPost Proceedings. And is supposed to report on the talk presented during the conference. In general, it does not represent unpublished work as it is not normally required for proceedings. We recommend expediting the acceptance and publication procedures if possible.
