Overstayed visa by 4 hours in 2015. Will that effect my present Chinese X type application?

In 2015, due to a delayed flight, I arrived 4 hours too late to the Luohu/ Hong Kong border crossing. I am now applying for my X type as I'm preparing to do my Master's in China. I have received the admission letter and JW201 form and am wondering if my accidental overstay will negatively effect my receiving the X type?

I did not have to pay any fines and was not detained, as it was due to my flight being delayed which I was able to prove. I however, had to sign a warning release ( A small sheet of blue paper with a red stamp).
