Gsutil bucket says all objects uploaded, files don't actually overwrite changes.

Linux Distro: Pop!_OS 19.10 Ubuntu

So I tried executing the command ```gsutil -m cp -r ejsout gs://evaapp.xyz``` to push to my storage bucket. TThe command copies all the files successfully, returning ```/ [333/333 files][ 19.7 MiB/ 19.7 MiB] 100% Done 998.4 KiB/s ETA 00:00:00
Operation completed over 333 objects/19.7 MiB.``` but when I go and look at the bucket online, the files aren't overwritten. Anyway to fix this? Feel free to close this issue because I'm bad at this and I couldn't find any helpful documentation on this.

Start by reproducing the reported `gsutil -m cp -r ejsout gs://evaapp.xyz` upload and verify the local files and bucket objects independently. Investigate the copy command's overwrite behavior and document the cause or a confirmed correction; done means the changed files are visible in the bucket after the command completes.
