Dataflow does not refresh column information in Projection

I am trying to make dataflow to read data from source and merging into sink table.

I am trying to achieve it dynamically by passing information in variables.

3 objects used in dataflow are reading information like dataset table name, query, Alter row conditions and key column in sink .

But when I run this for 2 different tables, the columns in projection tabs not getting refreshed. which causing issue in fetching information dynamically.

If there any way we can do it dynamically or its not possible as of now ?

    The issue was due to import projection on the sink and source, which have column structures stored within them.

    Re-created dataflow as below and it resolved the issue. User's image

    Thank you BhargavaGunnam-MSFT for your suggestion.

    I realized that my sink and source have column structured stored in it due to click on Import projection.

    I re-create dataflow as below:
