Martinize2 can not separate my protein chains...

[MarcosAR94]

Hi! Looking for human advice

I'm working with a homopentameric transmembrane protein following the tutorial, and I'm stuck at the CG conversion. Martinize2 is outputting my last 2 chains into the same itp file

having a molecule_0.itp, 1, 2 and what should be 3 and 4 is integrated into the same

I have already set a letter for each corresponding chain
having TER terms between the last and first amino acid residues when a new chain begins
and each residue has its own residue number, instead of having a repeating sequence of 340 numbers.

Issue here
