Storyblok CLI starts-with flag doesn't seem to work when syncing stories/folders

[EvaniCrossing]

Current behavior:
I'm attempting to sync a folder from space A to space B with the CLI, however the starts-with flag doesn't seem to take effect when running the following command:

$ storyblok sync --type folders,stories --source {source_id} --target {target_id} --starts-with {starts_with_string} 

In my case, that string is 'en' as I only want to sync the international folder (en/...)

Expected behavior:
I'd expect only the stories/folders that start with {starts_with_string} to sync, but instead it syncs all folders/stories.
