Attributes of Mapped Superclass do not show as Filter Properties

I am using version 6.8.0 of the Cuba Framework. I have created an Base Entity which is a Mapped Superclass. Other entities extend from this Base Entity. The Base Entity has some attributes, for some reason i do not see this attributes in Filter Properties in the UI. I am able to see the attributes of Standard Entity too from which my Base Entity extends.

This is the sample hierarchy for better undrestanding:
StandardEntity %Mapped Super Class%(Attribute:created_by) -> MyBaseEntity %Mapped Super Class%(Attribute:Team) -> MyClass

Filter shows “Created By” attribute but not the “Team” attribute in Properties

Please upgrade to platform 6.8.1. This issue could cause the problem.
