ADAU1777 problem with parametric EQ

Hi everybody,
my first problem that i would like to discuss in the engineerZone is the following:
-ADAU177 devBoard successfully connected under Windows10,
-input straight to output works.
-Likewise, it works to include any number of 2nd-order filters in the signal path.
-> But if I put a parametric EQ into the signal path and add more than two bands, something gets stuck.
The EQ is then somehow turned off and can not be reactivated, even if the individual bands are switched off again.
It is also strange that the simulated response (PROBE) nevertheless indicates the set transmission function.
Any Ideas?
Thanks a lot!
Kind regards
Simon
