Double Achievements

I have been entering scouts from our sign up night.
New scouts have a very clean achievements list.

THe existing scouts, that have been imported from scoutnet have achievements from prior to 2016, and those after 2016 for our choice in entering them. I understand this.
However, every existing scout has DOUBLE versions of these achievements possible.
I have to delete them for each scout to clean up their options…
Anything other than manually cleaning these areas can be done?
