Activities

Hello,
I sent my application to many universities. On the “Activities” section, I wrote :MUN instead of MUN Training." I participated in the training because the actual one is about to come (I am also participating in it). Does this error count? If it does, what am I supposed to do?
Note: I submitted it using the Common Application.

Hmmm. I think if you put an explanation for it you should be fine.
