Bug: bin_cols list not global in second phase of Jennis

[Shayantan1012]

Hello, I encountered an issue while running Jennis. The problem occurs in the second phase, where bin_cols is implemented as a local list. However, it needs to be global for the code to execute correctly in later stages.

After changing bin_cols from a local list to a global one, the issue was resolved and my code became error-free.

Could you please confirm if this is the intended behavior? Or would you consider updating the codebase to make bin_cols global in the second phase?
