A freelancer made this file for me. I am not very familiar with Illustrator and am Trying to change this text in all labels in one time not one by one. Could you please help,
They are all single text objects? Not symbols? Not an effect? Not the repeat function?
Can you open the layers panel, click on one of those texts on the artboard and then click on the magnifier glass in the Layers panel and show us a screenshot?
