OPA2992: Distorted amplifier waveforms

Part Number: OPA2992
Other Parts Discussed in Thread: TINA-TI

Tool/software:

Good day,

I am simulating an amplifier based on OPA2992 using TINA-TI. I get good results when I use the inbuilt battery in TINA-TI. However, I get distorted output waveforms when I power the same OPA2992 circuit with a DC-DC converter.

below are the waveforms

When I use the inbuilt battery:

and when I use the DC-DC converter outputting the same voltage as the battery?

How best can I get the desired waveform while using a DC-DC converter? Attached is the simulation file.
