DefaultDisplayUnit is not retrieved when a quantity is used as "label_quantity"
When we generate archives with some repeated sections, we use to indicate one of the quantity as our label to be shown in the subsections list (see figure below)
When the label_quantity is a string it's not a problem, in this case I wanted to have the time in seconds as my label_quantity and I see that the SI unit is actually used there.
I would like to ask to some fix for this. This issue might also be related to #932
maybe @mnakh?
