Possible 2.9 bug report - Copy To in patch using softkey modifiers

I'm following along the new training material released recently and in the level 3 video "Patch Features" after channel 101 is copied to 107 and 108 they go to Blind Spreadsheet to see channel 107 & 108 are now showing up in cue 18.  This doesn't seem to work in 2.9, I reinstalled 2.8.3 and tried again and it's working there so I don't think it's PEBKAC
