UCD3138HSFBEVM-029: Question about the main power bode diagram of UCD3138 full bridge hard switch development board

Part Number: UCD3138HSFBEVM-029

Greetings
I tested the main power bode diagram of the UCD3138-based full-bridge hard-switch development board.
The test waveform is as follows:

The main power simulation bode I got in the Fusion Design Offline software is as follows:


Why is there no resonance peak in the measured main power bode diagram?

It does not look like the main power of voltage-controlled. Looks like the main power of current mode control, why is this?
