Dot operator not working for nested CDT in Record Grid View configuration

Hi,

Have a service based record for which CDT has two level nesting. While configuring Grid View in 16.2, it gives the following Error :

The Requested Record Type Is Not Available
Expression evaluation error : A grid layout column [label=“Vendor”] has an invalid value for “component”. The component in row 1 encountered the following error: Expression evaluation error : Could not find variable 'rf!POHeader' (APNX-1-4198-000)

Expression which gives error --> rf!POHeader.vendor.vendorName

While using index() function it does not give me the error.

Using index() function --> index(index(rf!POHeader,"vendor",{}),"vendorName",null)

Dot operator should also work here as it works at other places like Record Title etc.
