Problem
When trying to save a new metadata field (in space or globally), the error "Title must be unique and must contain at least one character. Please choose another title." is displayed.
Solution
Special characters will be removed when generating the metadata field key. This may result in the same metadata key being used for fields with different titles. Please rename your field in such a way that it will not duplicate an existing field when removing all spaces, -, ., *, ä, ö, ü, ß, $, etc.
