Error in grompp step

GROMACS version: 2022
GROMACS modification: No

Dear All,
I am doing MD simulation of peptides and a ligand. I used ligand reader and modeler in Charmm GUI
to generate topology files for the new ligand. When I add it with other peptides and try to run grompp (Gromacs command) the following error was generated. Can anyone suggest to me solve it ?

The charmm36.itp file looks like this.

Thank you !

It may be that that force field files/parameters are included in the wrong order in the topology file. Topologies are hierarchical in GROMACS. Here you find more information about
