I would suggest disabling shulker box stacking entirely for each shulker box color in the item_settings.yml file, there isn't much benefit to them stacking and if it's causing this problem, disabling it will fix it. I'll have to look into how to actually fix this, I'm not sure which event fires for when an item is destroyed.
