Ah so that’s not really putting a slash in the name on disk - finder is just displaying the colon that way - it substitutes with a colon for historical reasons that have to do with pre OSX MacOS (but you can see if you create a file from a program or the command line with a colon in it, it will display as a slash in finder). It shouldn’t cause any problems on its own on the system - but the colon is troublesome if you have to interact with DOS/Windows lineage machines.
