Because you were farming attachments and other unlocks on Bots. Well deserved! EA allowed bot farms instead of hiding weapon packages/attachments behind a paywall! I should giggle really hard now. Enjoy your deaths counted into Bot farms, haha.
Bots should never be included in official statistics and should not be used in a progression system.
You're doing a disservice to yourself and other players by rushing into bot farms. You'll unlock things faster, but your general skill won't improve at all!
On the other hand, normal and sane players have a smaller pool of players to play with!
Bots should be available as a training ground, not a regular progression gap filler!
Congratulations!
What is this casual mode? It is a fast unlock/sweat mode to prop up a progression. I mean it! I will never farm on bots because it is counterproductive in reality. Once (bot farmer) goes into multiplayer, reality checks on him fast!
Some people do not have much time for gaming, but at least allow them to purchase some scopes and grips! I understand that. Stop sending them into pointless bot farms.
