I have old gala token (v1) on my trezor, I am wondering if there is a way to swap them into v2?

I have old gala v1 in my trezor which I never swapped, I realized today that I had to swap them last year, but I was out of crypto. Now I want to sell them and my erc20 address shows the number, but no value associated. I am wondering if I can swap them? Please advise!
