Supplier site dff issue in 12.2.3

Hi,

We are context sensitive dff's on supplier site and seeing some issue when we are trying to change the context and update the field, the data is not getting saved.

here is the example

Oracle 12.2.3

DFF Vendor Sites

Context A --> Attribute1

Context B --> Attribute1

Initially Context A is used to save value in attribute1, later on when we are trying to update to Context B and trying to save value its not saving anything and still shows old values for Context A

Thanks,

Hemant
