promo item added before sale price?

We have a promotion where a customer gets a free item if their order exceeds $150. This is ongoing. Currently we’re also having a temporary 44% off sale. We just got an order for $75 but the free item was still added to the cart.

Edit: I just realized that on this order, the sale price & discount price are still under $150, so how was this item added to the cart?

For the free promo item I have “over $150” as the condition rule, then $150 spent money as the condition of use, with the promo product item as the action. The sale I have is a category discount and the free promo category is not checked to be included.

Edit 2: In looking at the invoice I printed, the promo item says $0.00 as the price, whereas it usually says “Free”. There was a previous order that was over $150 that received this promo item & that invoice prints the item as “Free”.

Edit 3: I just tested it myself adding the same items to the cart that are on this order & my test did NOT add the free promo item to my cart.
