Auto-sell chests - sell messages more frequent than listed

Reporting as Major only as this could be pretty annoying, especially if it applies to the higher tier sell chests. The sell message says "Your transactions in the last 10 minutes", but the sell messages appear every 2 minutes (which is the sell duration of the tier 1 chest I have, although the messages are not in sync with the items selling). It also seems to be giving the sell amount for 2 mins rather than 10 mins (300 items) I assume it's meant to be every 10 mins (regardless of the chest sell duration) so it's less annoying
