It took me a few minutes, but I found the problem! On that profile, you're calling Template:Died In Military Service instead of Template:Died in Military Service (note the capitalisation of "in"). Apparently the one you called has previously been used, but is now "retired" according to the template page. That's why you got a broken version of the one you were trying to call.
I'll edit the broken one now to be a redirect to the current one; that way both template calls will work correctly.
