You should show us the calling code, I guess ...

> match (re-matcher reg report)
> found (re-find match)
> fmax-85c (second found)
> rfmax-85c (nth found 2)
> found2 (re-find match)
> fmax-0c (second found2)
> rfmax-0c (nth found2 2)]

> {:fmax-85c fmax-85c
> :rfmax-85c rfmax-85c
> :fmax-0c fmax-0c
