Products in your Prime Exclusive Discount, have been suppressed

3 of my product has been qualified to products in your Prime Exclusive Discount. So I added them and after few hours they has been suppressed.

Reason:
Your current discounted price is not being displayed because the reference price (list price/standard price) is not available.

Previously, I did not have a price list specified in the offer settings. From the beginning of creating the listing, I had a price in: Your price (£59) and now I have a lower price in Sale price (£29.99)

I edited listings yesterday and added price into List price (£59) (the same as “Your price”). I deleted current prime exclusive deal and create new one with the same sku (for the same products) and got email again that the listings been supressed.

Anyone had similiar problem. What to do with it?
