WinSCP to Docker Volume not listing all files and folders

I have Docker on a remote server running Ubuntu. I use WinSCP to connect to volumes for file editing and FTP. Sometimes, WinSCP does not list all the folders and or files in a volume.

For example, on a WordPress container, I have a volume for /var. When I connect to the volume with WinSCP, I can click on www/html which takes me to the wp-content folder. When I click on that, I only see 3 folders listed: cache, plugins and themes. There should be several others – aiowps_backups, languages, updraft, uploads, upgrade. (aiowps_backups is the one I mainly want to get to).

Also when I click on any of the 3 folders that are shown, they come up empty even though I know there are files and folders inside them – I have checked this by accessing the container through the terminal.

Well, (unless you have very specific filtering of files enabled in WinSCP, what I assume you don't) WinSCP is not hiding any contents from you. You are probably not looking in the right place. Or are you seeing those files and folders in any other SFTP client?
This is rather Docker or WordPress question, than WinSCP question. Please, consider asking at more appropriate site, like Super User or WordPress Development Stack Exchange.

It's ok, I figured this out, for some reason, the wrong name was attached to the volume.

Thanks for your feedback.
