Send routing panners not working properly??

If i create a stereo track (doesn’t matter which.e.g Audio,Instr, Group etc) I cannot access the send routing panners if I send to either a “MONO” group or FX track, it’s just greyed out, yet I can do this in all the previous versions of Cubase.

Stereo to stereo send routing is fine though…no greyed out boxes & I can pan away etc…

Please tell me it’s a bug & not a dropped feature!
