Google only has a limited amount of Structured Services available across thousands of categories that you can apply.

With the new Services Section added to the platform, you may be surprised to see that your Structured Services Tab may be left completely blank. Do not worry, this is not a bug, but a result of Google only having a limited amount of Structured Services available across thousands of categories you can apply to your business. If none of the categories you selected have a Structured Service associated with them, the live-spreadsheet will appear as blank (See Above).
Going over to your FreeForm Services Tab, you will see all relevant fields populate for you to add your own services to your listings. Once complete, just press the Update button and your services are now added to locations.
