Incorrect employment termination on F1 visa

[sawyer8]

Hi! So I was working at a campus job in my school up till December'23. I graduated in December but my school did not terminate my employment on my graduation by accident and I received pay for January. Will this create any issues down the line as it does seem that I was working illegally for a month before my authorized Post-OPT employment date in February? I have returned the payment but I am worried that this would show up as a violation on F1 visa status https://speedtest.vet/ https://vidmate.bid/ .
