Some parameters to fix the `invested unit`s not seem to work

[nnhjy]

Up to now, they include initial_units_invested, initial_units_invested_available, fix_units_invested_available

I will try building a toy example to reproduce the issue.

Hey @nnhjy were you able to pinpoint this issue? Can you add some more detail for fixing?

Thanks @clizbe and sorry for my late reply. I'll test whether it is an issue anymore.
