Label on shop page

I want to change some labels on my shop page. Specifically I want to change the term “OUT OF STOCK” TO “SOLD!”

I found this value stored in the en-us file and changed it but it doesn’t show up on the shop page:

“product_details_out_of_stock”:{
“title”:”Out of Stock Text”,
“value”:”SOLD!”
},

Where else is this value stored and how to change it?

Thanks!
