html code showing in cart for Price Matrix discounts

There’s html code (span) showing in the title for the discounts created by Price Matrix in the Cart. In my instance looks like:

26-50 Discount <span class=’ppom-option-label-price’>[+$1.45]</span>

To recreate, please go to this product link:

Choose a Material, Size and Color and order 26 or more, then add to Cart and go to Woocommerce Cart page.

Thanks
