No, it's fine. You clearly were not trying to make things worse. Also, the categories here tend not to be very well labelled, so one often has to get a sense of where things are just by looking around.

You were adding pages to Category:Episodes_using_the_old_airdate_system. This category is normally added automatically depending on what was put in the infobox on the page. Its purpose is to mark which pages do not specify for which country/region an "original airdate" refers to.

I was undoing your edits because there is a more specific way to flag the issue. An airdate without a reference immediately next to it should be marked with. This adds the page to Category:Citations_needed.
