Mech-Vision step missing

Hi guys, I try to find the step ‘invert pose’ as you showed in the picture but I can’t find the step. Can you tell me how to find this step or is it the version issue? I use the version 1.7.3.

Please have a look at this screenshot. You have to expand unfrequently used steps and then you will see this invert pose step. By the way, you can also upgrade to the latest version 1.7.4, which you can find in this link:
