Repeated warning while co-simulating using PYNQ- Z2 board

Warning: OPMODE Input Warning : The OPMODE 0110X0X with CARRYINSEL 000 to DSP48E1 instance is invalid.

This is the error I am repeatedly getting while co-simulating it on the PYNQ Board. My simulation and synthesis work perfectly. How may I resolve it? What may be the possible reasons behind the warning?
Kindly advise.

These are the options I selected while co-simulating.

This isn’t a PYNQ issue.
You would be better searching/posting on Xilinx forums.
