This might be a pretty novice question but I am trying to coarse grain a basic molecule of styrene. I have it's PDB file as follows:

I saved the above PDB file as ST.pdb, and ran the following command:
martinize2 -f ST.pdb -x STc.pdb
It gives me the following output:
INFO - general - Read 1 molecules from PDB file ST.pdb
INFO - step - Guessing the bonds.
WARNING - unknown-residue - Can't add bonds based on atom names for residue S-STY1 because 'Residue STY is not known to force field charmm'. Falling back to distance criteria.
INFO - general - 1 molecules after guessing bonds
WARNING - general - Mutation "cter" not found. Check target resid!
WARNING - general - Mutation "nter" not found. Check target resid!

ERROR - general - 4 warnings were encountered after accounting for the -maxwarn flag. No output files will be written. Consider fixing the warnings, or if you are sure they are harmless, use the -maxwarn flag.
I am confused as to what is going on here, even when I visualized ST.pdb using VMD it looked perfect:
