EWM Auto create pick HU for each Task on a Warehouse order

Dear Experts

We've got a specific need for EWM to automatically create Pick HU's for multiple tasks on 1 warehouse order.

Packspecs are maintained, with HU creation tick on in the packspec.

HU creation is also ticked in the packaging profile, as well as the "Assign HU's to WT's" tick.

But, the system only creates 1 pick HU for Warehouse Orders with more than 1 task. (system creates a task for each level qty of the packspec)

Any idea why the system does not create the other HU's? Any idea where I can look further? Cannot determine the issue from the log during WO creation.

I have had a look at this thread  with no help as well:

Pick HU not created automatically in EWM
