Two raids uploaded as one

Hello! I’m terribly sorry to waste time if there isn’t a fix for this, but I thought I would try at least.
I’ve just recently started logging for our new guild and with that I accidentally uploaded our Normal raid alongside our Heroic in one go. I’ve already deleted the file as I do-so after uploading to save space. I will definitely avoid that in the future to try and steer clear of issues like this again. I was curious as to if there’s a way to delete the normal content I’ve re-uploaded so that heroic is on it’s own on the correct calendar day?

Here is a link to the log I’m specifically addressing:

Thank you and terribly sorry for such a silly mistake!
