[BUG] Some actuall empty metadata seems to be stored as " " string with space. #17
Description
It seems some metadata is stored as string " " with a one character space instead of an empty data. That could be lead to incositancy or visual problems on text fields. See attached image where the original hint is not shown.
For example if images are loaded, I need to check if its already stored like this in the database or its loaded like this. Maybe also implement a repair mechanism to check fields if project is loaded
