Insane Number of Unearned Intensity Minutes

My new Venu 2 is registering an insane amount of unearned intensity minutes. Last week to was 946 with zero exercise. There were normal activities like throwing the ball to the dog and mowing the lawn, but nothing major. 

There was also one night where I had a few drinks so my HR was elevated. I earned over 300 intensity minutes during the night.

Anyone else seeing this?
