Confirming behavior of editing the templates works as it has typically worked which involved a bit of a different workflow.
In the Holdings Editor,
[1] Choose option to add holdings
[2] Set desired template fields for shelving loc, classification, prefix & suffix and Save Template.
[3] Add Call Number Label and Barcode and Apply All, Save & Exit to create the item
[4] Realize that you wanted to add more to the template, so you reopen the item; add all desired template fields again by hand (not by applying previous template), set an additional field like the age protection field; selecting the same template name you want to update, choose Save Template.
Edited to add: Item Fields no longer have to be manually applied when editing a template - just applying the template works; the holdings fields now included in the templates are behaving differently but it does work with the manual update process
