No schema for the file verification found.

Hello,

When running a QA check in Studio 2019 on a project which is published on GroupShare 2017, I get the Warning messages "No schema for the file verification found." from the XML validator.

These Warning messages all disappear as soon as I validate a segment (even if made no modifications).

Could you please advise on the issue and it's resolution as I would not like to me missing important error messages.

Thank you in advance.
