Ranking issue with particle stoichiometry

Hi,

When simulation a charge pulse of 180s, I have the unlikely ranking:
Maximum negative particle surface stoichiometry > Maximum negative particle stoichiometry.
I have tried to increase the number of points in the anode, but in vain.

I use:
PyBaMM: 24.5
Python: 3.12.5

See attached file.

Bug ?

NB : just started using PYBAMM two days ago, so I may have done a mistake.
