Adwords is a very nuanced datasource. Certain fields don't work with other fields, and oftentimes this is very specific.
If you get this error in Grow:
Error: Invalid field selected. Please review your query and try again. , it probably means you are trying to use 2 fields or columns together that Google Adwords doesn't support.
The best way to check this is to read the documentation Google provides here.
For example if I am trying to pull 'Device' and 'BounceRate' and I get that error. I would go to the Google Documentation, search for those two fields and read the "Not compatible with the following fields:" section, and find that Device and BounceRate are not compatible.
