Drawing note adds trailing zeros

Hi all

So I created a custom property called Thickness that pulls a value from the thickness global variable.

The value shows in custom property as 4,50.

But when I create a note and link it to this custom property of the component the note displays as 4,5000.

Please see attached images.

Any advise for a work around or fix would be appreciated.
