RFSoC 4*2 DAC sampling rate problem

Device: RFSoC 4x2 Kit
PYNQ Version: v3.0.

I am rebuilding the RFSoC 4x2 MTS project and have changed the DAC sampling rate to 8G and the ADC sampling rate to 4G.
I successfully loaded this bitstream file in JupyterLab and managed to output a custom waveform to the DAC memory.
When I connected the DAC to the oscilloscope (maximum frequency of 70 MHz) using an SMA cable and set the frequency to 10 MHz in the code, the oscilloscope displayed 5 MHz. What could be causing this discrepancy?


Below is my code, bit, hwh and RF data converter settings
