Classification Rule Builder Snafu: None Bucket in Creative Elements - and not grouped under none bucket for Parent Classification/Rule i.e. Campaigns Parent. How is this possible?
Curious if anyone knows why we have a giant none bucket under one of our campaigns parent classifications/channels and it somehow isn't all grouped under the None bucket for the parent classification i.e. Campaigns parent. Anybody know how/why this could happen? Its going back quite some time and I was told that it was because of a misclassification error that I made that had a 1 month look-back window. Basically I put an extra separator in a regex rule that ended up like a catchall and put all the tracking codes under one channel of campaigns. However it only had a one month lookback window and when I reverted it a few days later- I was told that I apparently had caused this none bucket to incur more unclassified/misclassified tracking codes- but I'm not sure how that can make sense.
TL;DR:
1) Does anybody know how/why Campaigns Parent has a None bucket with misclassified tracking codes and when I go to a channel in campaigns parent and break it down by Display- how does that have a none bucket as well?
2) Is this from a historical error of misclassifications? Could this be the result of the one month lookback I did with my classification rule error - which I had corrected after it being noticed after a few days?
Side Note:
*I'm assuming that maybe it had to do with an old misclassification that had somehow been classified by the campaigns parent channel that this none bucket was appearing under- and that maybe it didn't have a creative elements classification rule and that somewhere along the line maybe these rules were removed- which maybe is why I can't see it at bald face/front-and-center any rules that could have caused this. Just wanted to make mention of this as well, because the classification rule builder is an increasingly confusing tool and I'm a little hesitant that I caused this break and that maybe historically there was some misclassifications in the past that had already been removed before I had come on the team, but I'm not sure how it's possible and hoping for some confirmation/explanation on this. Thanks in advance!
