I clicked on the wrong pet when I was asked to:

"Task: Change Autobattle Settings to 1 Bite, 3 Blow and 5 Rush to make the best of the next fight."

It will not let me click on the proper pet so I can complete this section!

I dont know what to do

I checked your data, you have the right pet selected (the one you adopted from the pound). Please proceed with the tutorial instructions.
