Simscape Gear constraint example throws position violation

Hi, I'm trying to figure out how to add a gear constraint between two joints, so I thought it would be a good idea to start with a tutorial. So I run this command in matlab "smdoc_common_gear_external_start" to get a gear example and when I simulate the model I get this error:
['smdoc_common_gear_external_start']: Following errors were found in the model smdoc_common_gear_external_start. Caused by: ['smdoc_common_gear_external_start']: * Model not assembled: position violation * Resolve this issue in order to simulate the model.
The model has not been changed at all, tools -> model reporter shows that it's the gear constraint that has not been assembled, and all the axes of are aligned. Does anyone know why this happens?
It's from 2017b on windows 7.

As written in the documentation, the model "smdoc_common_gear_external_start" is incomplete. You have to enter the correct parameters in the rigid transform blocks to assemble the mechanism. Check the documentation below on how to complete this model. https://www.mathworks.com/help/physmod/sm/ug/satisfying-gear-assembly-requirements.html
