Most likely:
Rear spheres (you have 4 of them, 2 for the stiff corners, 1 for the soft ride, and one to act as a rear pressure accumulator) low on pressure.
Your car will have anti-sink valves, when the pump is running the pressure on that side of the valve opens it, when the pump stops the pressure in the sphers closes the valve keeping the car up.
If the spheres are low on pressure then they don't close the valve fully so the end sinks.
Could also be:
Internal LHM leak where it's getting past the rear strut pistons and returning to the LHM tank, leaching away the pressure.
A leaky hydractive block (the thing that switches the suspension between hard and soft by isolating the hydractive sphere) could also do it.
