OK but why AD19 is not able to find the right values?

Seems OK with 50 Ohm impedance but always getting a very small track for 120 Ohm.
I should have something like 0.12 mm.

I tried to enter the attached stackup from my manufacturer.
Now it is no more possible to reach 50 Ohm impedance...

Any idea maybe?...

It is not possible to move L1 down.
It is not possible to add any layer above L1.
So I don't the way how to proceed.

I didn't start any routing. Layers are empty.
I just would like to have the following stackup:

I have a quite big schematic with several variants.
It seems to be OK.
Thanks to JohnsonMiller...

I have noticed that:
If I remove the component on a sheet and place again the same one, I don't have any trouble.
