Can you file this as a service request on the Altera website and attach the system and custom instruction files. I have a hunch what is happening here and I think you are running into a bug (in both cases) that I don't think can be easily worked around.

For now I would create a non-HDL parameter into your .tcl file and append it to the end of "SYNCHRONOUS". That way when you add the CI you can ennumerate them to avoid the overlapping '#define SYNCHRONOUS'.

I think this should work assuming you call the non-HDL parameter "ID" and the combined name "UNIQUE_NAME".

append UNIQUE_NAME "SYNCHRONOUS", $ID

Then you would use "UNIQUE_NAME" to create the macro for the header file. You could use ID = 0 for one CI, and ID = 1 for example make sure there is no overlap in names. Note I hate .tcl so you might need to tweak that code a bit to get it to work :)
