Thank you @Kusuma04-dev for your PR!

IINW, with this change the logic will automatically nest a List Expression inside the created List Expression, as shown in the below image

This is not the expected behavior, we should keep the expression undefined so the user can manually assign the expression to set there.

Based on that, I think you should revert the change and continue your investigation, the bug is in another place, in my opinion.
