Have the following options been set up? Also, is this phenomenon occurring in simulation?

Port n Local ackID CSR
This register returns the status of the local ackID for both the input and output sides of the
corresponding port. This register is available only if the software assisted error recovery
option is selected in the Vivado IDE.
