Data not showing when using Line Tool

Hi . . . I’ve recently updated to Cubase 11 and so far all seems excellent except for this one thing. I frequently use the line tool in the editor to set velocity levels for Instrument tracks but I’ve now found that the velocity level is not being displayed as I use the tool.
Is anyone else experiencing this problem? If not, maybe there’s a setting somewhere that I’m missing!
Thanks . . . Martin
