<!-- Please describe your changes on the following line: -->
Relates to #20332.
This PR intends to refactor `counter_style` to use `parse_non_negative` where applicable, mostly which uses `expect_integer` currently. Change still grabs value from parsed result then assign it into each struct as needed and does not change definition of struct (i.e `AdditiveTuple`) itself.
