How can I fix the error: "colleagues overdefine assembly"

Hello everyone, I have been making a hydraulic arm for a university semester project. Summarizing my problem, when assembling my clamp my intention was to use "revolute" on one of the arms of the clamp but I got an error and my design stopped working properly, I would be grateful if someone answers my question. Thank you
