How to remove the 'CS_' symbols for server call function name in generated ARXML

When I generate the code of my AUTOSAR model, I find there comes out a 'CS_'symbol as my server call function name prefix. Besides, this situation happens to Sender-receiver port also, where the 'In' or 'Out' Prefix appears at inport and outport name correspondingly. That's not friendly to AUTOSAR Round-trip development.

Although I have tried my best to modify these setting in Code generation setting, these annoying prefixes are still there.

Thanks in advance whoever could help me out!
