Message server port of ECC system

Hi

I was trying to create a Technical system for ECC system in SLD. I reached the Central Servers tab. I have to add the Message server port here. It should be ideally 36xx followed by the instance number.

I checked in T SMMS, and saw that the parameter is incorrectly added there. It's 36xy, the instance number plus one.

Will this effect the message flow in future. I am not a BASIS consltant and I want to know whether I need to correct it in ECC or add it as it is ECC in the SLD while configuring Technical system
