Skip, Stop, Replace warning messages on MacBook with macOS Sonoma.

I just copied a folder contents from my Mac to my MacBook Air.

Usually when a file already exists a warning comes up and asks if you want to Skip (Keep Both), Stop or Replace.

Today it didn't it just dumped the whole lot and added a "2" to the filename!

Now I have to go through and manually delete all those duplicates. 🥲

Can anyone advise why this has happened and how I get it back? I can't find anything in settings for either Finder or System.

Thanks very much.

if something does not work as expected Command Z will undo your last action...
