Hydration App Not Resetting

I've seen this was previously an issue with Venu 2, but even after synching the Venu 3 with Connect App, the hydration widget on the watch hasn't reset to zero.

I've set my daily intake to 3,000ml, and yesterday added 2,250ml of intake.  This morning it's still showing 2,250, and I can add more intake to this figure.  After syncing with phone, the widget is still showing 2,250ml.  The expected behaviour is for this to reset to zero at 00:00 I presume?

Known bug?
