using "." (dot) in remote names, remote is not working

[supervisitor]

I've found that there's a point/dot in the name that renders the remote configuration unusable!

e.g. a working configuration with correct name:
[working_name]
type = http
config_automatic = yes
url = https://user:pass@example.com/myPath

e.g. a configuration with a not working name for remote:
[notworking.name]
type = http
config_automatic = yes
url = https://user:pass@example.com/myPath

with a dot inside the remote name I always got a empty space (folder icon with label: "The folder is empty") and error message: "X Error retrieving directory content"
