My drama stats changed?

Hello! :)

I'm confused. My list of completed dramas changed; it's now 1100 dramas, and I am pretty sure my stats showed 1250+ dramas watched before. The stats of the profile and the list were different, but still not 1100 dramas. Was there any change in the way it was counted, or were some dramas deleted?

I'm pretty sure I didn't delete any drama myself unless there was a bug!

Thank you :)
