Hi,
the field "Aisle" is empty. If you have set up your bin structure correctly, this field would be filled. Correctly means that you use the "bin identifiers" you have defined in customizing under "Define Storage Bin Identifiers for Storage Bin Structures". The standard for the aisle is "A", but maybe you have set it up differently or not at all.
The screenshot of your bin also does not contain a bin type, which is shown in the structure definition. Are you sure this bin was created by the structure?
