Got a provisional acceptance in a college, afterwards found out i forgot to include a class in the self reported grades

So title, I got a provisional acceptance in a college, currently I haven’t sent my official transcript to them so that they can verify it. I was going through my self reported application and found out I forgot to add Spanish 1 in 9th grade.

Is it too late to contact them about the mistake, or does it not matter because they gave me a provisional acceptance (despite the fact that I have spanish 2 in 10th grade, but am completely missing spanish 1) after they read the self reported grades?

If it wasn’t a good grade, then it may look suspicious and you should contact them to explain. Hopefully it’s not a big deal. Good luck!
