Problem with [line(Point,DirectionVector)] command, GeoGebra 3D

Not a Problem

On the desktop app as well as in the online app the [line (<Point>,<Direction vector>)] command is malfunctioning. The entered parameters for the direction are modified when executing.

The 3rd parameter seems to be the problem, as it will sustract 1 to the number that was enterred, for example, if you type (1,1,1) GeoGebra will use (1,1,0) as your Direction vector instead.

you are using line(point,point) if you want line trough (0,0,1) with direction (1,1,1) you must type

Line((0, 0, 1), Vector((1, 1, 1)))

if you have u=(1,1,1) as vector in the algebra list you can type line((0,0,1),u)

when you type u=(1,1,1) you get a vector by default; when you type (1,1,1) or U=(1,1,1) you get a point

Thanks a lot!
