Woocommerce and Storefront Tax Calculation Bug

In my testing site, I only have WooCommerce and the Storefront theme, nothing else.

I have a test product that is $0.01. I can add it to the cart and checkout it calculates the total with tax properly (still $0.01).

When viewing the order in Admin, if I update the order in any way (simply hitting the “Update” button), the tax calculations get astronomical and the order total becomes $10.81.

In Colorado we have to collect several local taxes:

WooCommerce > Settings > Tax > Standard Rates:

Country	State 	Postcod	City 	Rate % 	Tax name 	Priorit	Compnd	Shipping 
US 	CO 	* 	* 	2.9000 	CO tax 		1 	o 	x
US 	CO 	* 	* 	1.0000 	RTD tax 	2 	o 	x
US 	CO 	* 	* 	0.1000 	SCFD tax 	3 	o 	x
US 	CO 	* 	* 	0.9850 	County tax 	4 	o 	x
US 	CO 	* 	* 	3.5000 	City tax 	5 	o	x

During checkout, the taxes calculate properly to this:

Items Subtotal:		$0.01
Shipping:		$0.00
CO tax:			$0.00
RTD tax:		$0.00
SCFD tax:		$0.00
County tax:		$0.00
City tax:		$0.00
Order Total:		$0.01

After clicking “Update” the tax rates recalculate to this:

Items Subtotal:		$0.01
Shipping:		$0.00
CO tax:			$0.00
RTD tax:		$0.00
SCFD tax:		$1.00
County tax:		$9.80
City tax:		$0.00
Order Total:		$10.81

It seems that the two taxes that are less than 1% (SCFC and County) are the two that are calculating improperly. Can you help me figure out how to correct this?

Thank you!
