Double Tiered Quantity locations?

On our WP backend, in the edit>product page there are fields to enter tiered pricing on the “General” tab and a tab titled “Tiered Pricing” which has a “Minimum Quantity” Field. Since we are using a few tiers in the “General” tab, the other tab adds another row to the front end table that is displayed, which is an unneeded duplicate.

How can we hide/disable the “Tiered Pricing” Tab? I see you answered this question here: https://wordpress.org/support/topic/minim-order/ but not sure if this still works, or where to put the code. (We tried following but were not clear on the instructions)
