Please try to disable or enable the "Split address into multi lines" setting on this page.
When the setting is enabled, the tool uses the different components of the address to create an address split into multiple lines. In order to achieve this, your locations need to have the single address components (address line 1, address line 2, city, state, postcode, country).
If you imported your locations through a CSV/XLSX import or by using the Google Sheets Sync tool, please make sure the address component columns are not empty.
If you added the locations manually from the dashboard, the address components won't be filled in and your locations will have the address into a full string (not split into different fields).
