Managing upgrade risk - Washington DC

[valentin3]

Hello guys, 

We have an issue since the new upgrade at Washington.

They introduces a new feature called "Managing upgrade risk", and after reading the documentation Link to official documentation I understand this warning message should appear to "high priority metadata files".  I understand this would mean OOB Script Includes, BR, Client script, etc..

But we receive this message on a variable of a custom catalog item and I don't understand why. 

I cannot find more documentation about this and neither where I can find the message in the platform. 

My issue is that I don't understand why it poped up on the custom variable? 

Can you help me, please? 

Thanks,

Valentin
