Woocommerce Checkout Page infinite reload with Wp-Statistics

Whenever an anonymous user adds a product into woocommerce cart, and proceeds to checkout, the Checkout page Ajax loader goes into an infinite loop constantly reloading the page every few seconds.
After extensive troubleshooting, and combing through access.log, I noticed the wp-statistics calls, and thought I’d disable the plugin to see if it made a difference, and voila! all my headaches disappeared.

This is a big deal for me as it is preventing customers from completing their purchases. (tripping at the finish line).
This will also explain why it doesn’t affect admin users. (I exclude admin users from stats)

I re-enabled the statistics plugin and I added /checkout/ to the excluded pages list, but the problem persists. This setting doesn’t seem to work at all. I also tried with /checkout (no trailing slash) as well as the full URL, but it had no effect.

Only after I disable the stats plugin does the page stop reloading continuously.
Any ideas how to fix this?
