BTW, AppleSpell.service is a package file. See attached. I don't know whether the AppleSpell file you have in Services is the actual AppleSpell file, or whether the package has become misnamed by losing its suffix. Maybe you could make a copy of it on your desktop, rename the copy to AppleSpell.service and see if you can see contents of the package by right clicking. If it shows up as a package, it may simply be a matter of renaming the file. (Check to see if the contents of the package correspond to my screenshot.)
