Minor glitch in LWH units

[Elnino]

Hi there,

Just want to notify a small glitch, nothing critical.

Running J1.7.3, VM 2.0.0-RC-2M

In shop config if you set up the default LWH units to centimeters for example it works great when you creat a new regular product.

But if you create a child product from a regular product that does not have LWH parameters completed (left blank), the default LWH unit for any new child product is still set to "meters".

Cheers.
