NIOS-V QSYS Warning Properties (associatedClock) have been set on

Hello,

I have a really basic setup of a NIOS V system, but get Warnings in QSYS (using Quartus 25.1 Standard) about Properties of associatedClock:

System:

Warning: 

Warning: nios_subsystem.intel_niosv_m_0: Properties (associatedClock) have been set on interface reset - in composed mode these are ignored
Warning: nios_subsystem.intel_niosv_m_0: Properties (associatedClock,associatedReset) have been set on interface instruction_manager - in composed mode these are ignored
Warning: nios_subsystem.intel_niosv_m_0: Properties (associatedClock,associatedReset) have been set on interface data_manager - in composed mode these are ignored

Questions:

1. What is "composed mode" and how can I control it? There is no NIOS Parameter associated with it
2. This appears in a basic setup simply by adding NIOS V to the system. How do I get rid of this warning?

best regards

Fabian
