Incorrect name on a new division

When setting up our new match, we accidentally forgot to put an S on the end of limited optics. I am unable to up load to USPSA now. How do I fix the file so I can send it?

We use to be able to correct the file but now we can’t. Any help would be greatly appreciated.

Though I wonder how did you managed to make an USPSA match without LO? The match templates and the web site been updated a while ago.

I think because I clone the previous match and just change the dates that I manually went into properties of the division field and added option item LO.
