Clutch no longer goes back, lever remains pulled.

Hello together With my Mondial HPS 125 (equivalent engine like RS 125) from the year 2018, the following problem has been revealed. After screwing around the clutch lever and at the pull-out lever, they no longer go back to their original position after letting go of the clutch lever. Since I have no idea of motors, I went looking for tutorials. But I found nothing that would take me further. So I emptied the cooling fluid and the oil and I did not find anything to do with it. d opens the engine to see how the mechanism works. In the attached image the point at which the pull-out lever starts is circled. Had someone ever the same problem, or can even tell me how to proceed and what needs to be exchanged. Thanks for every tip Gruss Many
