Ikea Siphon Atlant - Siphon rotates

Hey Ikea expert!

I designed and assembled a kitchen for myself at IKEA and am more than satisfied! However, a "small" problem is driving me crazy just before completion:

The siphon under the sink keeps turning away and thus disconnects the water outlet to the wall.
I could go crazy, really! Everything basically holds and is also sealed. But after a few minutes, there is a loud click and the outlet under the sink turns away. This negatively affects the silicone connection between the outlet and the wall.
I can't explain why because there is no tension on the hose and everything is tight at the sink as well.

Does anyone have any advice? :/

Best regards, Kathrin

Hello,
maybe the hose has not been cut to the correct length. Possibly a picture could help with troubleshooting.

Right, a picture would be very helpful...
