Remote server shows some files (.csv) in a particular directory but I cannot open those files or delete them. I have tried using Windows File Manager, FileZilla and also Command Prompt using ssh. When I run the following command

sudo rm <file-name>

I get the following output

no such file or directory

But when I run ls I can see those files listed I am completely lost. What are the possible reasons behind this behavior?

Edit:
Running ls -l returns the following
