Default Primary Waveform in the Half-Bridge SMPS

Hello, good day;

I've been testing my smps and observed that connect the output load peaks appear in the waveform of the primary, not square. I've seen some videos and also appears like this but I want to ask if this is normal .

If not normal or the fall is very high, tell me how to improve the functioning of my source and reduce these falls .

Thank you very much.
