We identified a issue with a Classification Rule for one of our clients. It is an odd case we have not found any documentation about.
While applying classification rule on the product values:
1. There is a classification rule created using a Regex, that sets one constant value as a result. Here is the expression:
.*Promo.*Streaming\s-\s[1-4]mo.*|MobileOAC:Promo - Premier Streaming - 6mo - 30.00 - 1moFO|.*Trial.*Streaming\s-\s[1-4]mo.*

2. When running a test on the set of values, they are all classified as expected (screenshot 2). Here is a sample product value that passes the test:
Trial - Essential Streaming - 3mo - 0.00 - 1moFO - wETF(6mo70) - AMZ DOT-G3

3. However when looking at the reports, that particular sample product value (and many others) are listed under "Unspecified" and not with the right value.
More than 72h have passed since the classification was created, and nothing has changed.

Do you have any idea on what may be causing this?
Thank you in advance for your help!
