Why is this causing a regression?

Why is this causing a regression?

Educated guess, but unfortunately benchmark CI is not working.

Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 9 comparisons, you can thus expect the following amount of false-positive results:
  0.45 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.09 false positives, when considering a   1% risk acceptance (**, ***),
  0.01 false positives, when considering a 0.1% risk acceptance (***)
