A disconnect between "compute pressure" and "press/berendsen" when bpm package is used in 2023 feature lammps

Hi jtclemm
my apologies for bothering you again, since you are the expert for the Granular package, if you do not mind, may i get some idea from you about this?
i currently got weird results for compute stress/atom results and I wrote a new topic for that. see

is this a potential bug or I made something wrong?

many thanks for your help. hope you have a nice day

best regards
