Midi Modifiers - Scale and Scale Note - Not working

If I create two instrument tracks,then play a riff.
Then select “Midi Modifiers” then “Scale” e.g.( Major) and then a “Scale Note” e.g. (D#)
The tracks are not in key. It’s out.
Then it will randomly remove the “Major” selection and return to " No Scale" Setting.

It’s not working for me at all.
It’s doing my head in.
It works in Cubase 3.
Because I’ve been using it for years.
Can anyone verify they have the same problem?
