Tacx Neo 2T and recover phases still request power

On my former Tacx flow smart, a recover phase was a recovery phase, I mean whatever the cadence, the requested power was low.

Now with my new tacx neo 2T, for the same workout, the recovery phases (with no target set) are hard as ***, I must decrease drastically the cadence to recover decently (<100W). It is like it stuck on the previous power level.
On the other hand, when I set a low power target, it works flawlessly.

Maybe should I set 'warm up' phase instead which work as expected (free pedaling no particular high output).

Has someone already encountered this issue?
