Then I tried pasting just 1 line at time (one keyword combination) to discover that a different Expanded Broad Matches showed up, so now I don't know if pasting more than 1 keyword combination do not show complete results and we must test one keyword at time, or if google changes Expanded Broad Matches according to the complete keyword set in the AdGroup, so we must enter the complete keyword set at once to see real results.
There is no help on this issue, and is very important, this detail is an huge detail!
