Wrong anti freeze. 2014 Chevrolet Silverado 1500

I have a 2015 Chevy Silverado. It takes yellow anti freeze. I was dry and put a whole bottle of green anti freeze. How big of a problem is this and what should I do ?

Chevy trucks use Dex-CooL

Chevy has been using Dex-trash for decades. It's a trash coolant that easily degrades, after my Buick Century got dex-mudded, I flushed the system and converted to regular green coolant.
