Restore doesn't display empty directories (Web UI)

I have a filter that excludes files but includes directories, which I assumed wasn’t working because the directories aren’t listed in the Restore interface.

But when I restored the whole Revision folder the directories were recreated properly, so they’re present in the backup (the filter works properly) it’s just that the Web interface doesn’t show them.

(I’m running the latest version, Duplicacy Web Edition 1.6.2)
