S340 recording motion events even though not selected

I have an S340 solar camera connected to a Homebase3 and in the last couple of days it has started to record motion events even though I dont have motion events ticked. I only have Human Detection selected.
There is no notification sent for these motion captures but there is a video captured which I can see in the Events.
I have noticed that the Homebase3 seems to have had a firmware pushed out to it in the last few days, I am now on version 3.4.6.9 (03-23 02:19) and think the two things might be related?
