Great question. Without seeing the exact wording it’s impossible to know.

My guess is that they use the term “base rent” or something like that. They could argue that regardless if the renewal is the automatic to month to month or if there was a renewal of a fixed lease the notice meets the base rent 60 days notice criteria regardless.

The challenge here is that OP would most likely have to take them to court to contest without a strong sense of if they would win or not, which risks even more in legal / lawyer fees if they loose.

Grey star is a massive company with lots of properties in WA. The chances of them not wording things in a way that doesn’t benefit them is unlikely.
