Thank you very much for your valuable inputs. !!
There is an extra fluid reservoir for the clutch and it is filled with break fluid. It sits right beside the brake fluid reservoir (2019 +4). It seems that Morgan changed the layout after 2018.
As Luddite is suggesting, the fluid moves when the clutch pedal is pushed.
I will let you know about the diagnosis by my Morgan garage.
Regards from Switzerland.
