The red color of the graph indicates that there is no connection between the grip and the controller.
Therefore, all subsequent screenshots from JoyTester are not informative. This can be assumed without 100% confidence.
I propose to remove the handle, gently wipe the contact pads of the connector with alcohol (or its equivalent, but not solvent). Look for 3 pins and their free movement.
Connect the handle and reset the controller to default with the button in the configurator. Until the error rate becomes close to 0% on the chart, further adjustment loses its meaning.
Believe in luck and she will turn to you the right side

p.s. specify the grip version more precisely - Pro, not Pro, left or right. It is important.
