Gromacs mismatch

GROMACS version:2018
GROMACS modification: Yes/No
Here post your question
Kindly help me deal with the mismatch below. Am using Gromacs 2018 running a gromacs tutorial 5. The chloride ions in the topol.top file are written as CLA. when doing the energy minimization while maintaining the ion as CL. am told no such moleculetype exists and when i change it to CLA i get a mismatch:
Warning: atom name 33501 in topol.top and solv_ions.gro does not match (CLA - CL)
Warning: atom name 33502 in topol.top and solv_ions.gro does not match (CLA - CL)
Warning: atom name 33503 in topol.top and solv_ions.gro does not match (CLA - CL)
Warning: atom name 33504 in topol.top and solv_ions.gro does not match (CLA - CL)
Warning: atom name 33505 in topol.top and solv_ions.gro does not match (CLA - CL)
Warning: atom name 33506 in topol.top and solv_ions.gro does not match (CLA - CL)

WARNING 1 [file topol.top, line 24633]:
6 non-matching atom names
atom names from topol.top will be used
atom names from solv_ions.gro will be ignored
