maybe if typst's version above 0.7,there is a bug about counter of affiliation_counter

[Schweik7]

in my pc,first affiliation's number is "-",not "a"; second affiliation's number is "a",not `"b".

so i moved counter's step award

affiliations [
      #affiliation_counter.step()
      #super(affiliation_counter.display("a"))#h(1pt)#emph(affiliation)

Thanks for catching that!

I've implemented less hacky solution by updating the counter to 1
