essay flagged for AI

Both my essays for a ge course im taking over the winter session were flagged for AI. I didn't use AI to write either at all. Some people have told me to use version history as proof but my professor said that it doesn't prove anything and I still have a zero for both essays. They were supposed to be based on two separate films which I did ntot watch but instead read a handful of summaries for both. I did not plagiarize anything either I wrote everything myself. What am I supposed to do going forward?
