Can’t unzip files

Hello, I am no longer able to unzip folders in the files app. Before I could click on it and it would automatically unzip but now it just makes it bigger and displays a “Preview Content” button.

I can look at the photos in it but there’s no option to unzip. I’ve tried holding it down but no option appears.

It worked perfectly fine before I don’t know why it isn’t working now, what do I do?
