Creating Task from volume zip: empty bbox not replaced by full one

[fm3]

In the task create view (not bulk), using a volume tasktype and „from NML“ option with an existing volume zip that contains an NML without a specified bounding box.

Expected Behavior

Resulting volume tracing should get full bounding box of the dataset (this is the behavior for explorational volume uploads too)

Current Behavior

The resulting volume tracing has an empty bounding box (0,0,0,0,0,0), essentially making it useless as no volume data is ever loaded.
