Validation error in Branding feature

Since the deployment of the version 54, a validation error is displayed in the branding feature:

The login logo image '' referenced by the branding configuration is not defined

When the radio Apply Application Logo is set to 'No', the login logo section is enable and an empty image is defined for the logo.
When the radio Apply Application Logo is set to 'Yes', the login logo section is disabled and it's not possible to remove the empty image.

Workraound :

• Set "Apply Application Logo" to No to activate the Login Logo fields (if not already set)
• Click on the little trash in front of the "Logo image" field to remove the empty value
• Set "Apply Application Logo" back to Yes (if you actually want to apply the application logo)
• Save
