Matching SKU product in automation

Hi to all,
I created an automation to send cross-selling emails to all customers who purchase specific products.

The automation start condition is defined when a customer places an order.

I’ve entered multiple conditions to verify SKUs using the syntax: “SKU of the latest product” CONTAINS a substring of SKU product. For example “Contains B1700” should intercept all products that have SKUs starting with B1700 (B1700.01 and so on).

The automation works correctly but it seems that no product respects any of the conditions set and no mail is ever sent while I am sure that more customers have purchased products that had to match the rules set for sending the mail.
I also tried to change the rules not using product SKUs but categories, but the result doesn’t change.

Can anyone help me?
Thank you very much
