error in defining top-level parameters on WEST2017

Hello,
I would like to define some kinetic parameters in my model as top-level parameter and receiving the attached error
"Parameter 'Param1' can not be created:Invalid key: Duplicate key in manager: LayoutManagerParam, Param1".
I am working on 2017 version and the description on the manuel seems different than what I have. I could define top-level parameters on another model in 2017 version.

Do you have any idea why this error is occuring currently?

Thanks in advance!

Hi Gamze,

Does the error occur when you drag and drop multiple parameters at once, or also when you drag and drop a single parameter in the Top-Level Quantities dialog?

for both situation.
It only occurs for the parameters. I could define temperature as a top-level parameter on interface variable section by drag and drop without any problem.

Hi again,
I could define the parameters that I want as top-level parameters at the end. However, I am not sure why the problem occurred before and how it is fixed. I did not do anything different than before.

Thanks for your attention.

Thanks for the update.
There may have been some inconsistencies in the 2017 version for Top-Level Quantities (as you have observed), but they have has been fixed in the new 2020 version.
