GROMACS: gmx grompp, version 2020.2
WARNING 1 [file topol_dppc.top, line 25]:
The GROMOS force fields have been parametrized with a physicallyvincorrect multiple-time-stepping scheme for a twin-range cut-off. When used with a single-range cut-off (or a correct Trotter multiple-time-stepping scheme), physical properties, such as the density, might differ from the intended values. Since there are researchers actively working on validating GROMOS with modern integrators we have not yet removed the GROMOS force fields, but you should be aware of these issues and check if molecules in your system are affected before proceeding. Further information is available at https://redmine.gromacs.org/issues/2884 , and a longer explanation of our decision to remove physically incorrect algorithms can be found at https://doi.org/10.26434/chemrxiv.11474583.v1 .

Too many warnings (1).
If you are sure all warnings are harmless, use the -maxwarn option.
I don’t understand the reason for this error. Can anyone help with fixing it?
