Issue with random discounts being granted

Hi there,

I’m using the REDIS discount plugin to create a 10% discount when more than 3 items are in the cart.
For the most time it works as it should but sometimes customers get random discounts on their order, making the order practically free.
It (occasionally) happens for all customers no matter the cart amount.

Here is one of the orders:

And here are de Product Pricing rules ( Cart Discount is disabled )

Any help would be greatly appreciated.

Thanks,
Oscar
