Can not group clips

Seems like there should be a really obvious answer to this, but I can't find one.

I can't get grouping of clips to work.

I select multiple clips, hit Command + G

I know it's grouping them on some level because if I select the Clips dropdown the option is now "Ungroup"

However, having them grouped doesn't seem to do anything.

I believe I should be able to select and move one and the other grouped clip(s) will also select and move, but this isn't happening! I select one after grouping, and only the one gets selected, and if I move it, only that clips moves.

It's making me crazy!

Is there anything obvious that could be causing my clips to not link??

I've tried audio + video clips, audio+audio, video+video clips. Tried grouping 2 clips and tried with large groups as well.

Nothing works!

Also not sure about the difference between Link and Group, but have tried Link as well for any combination of clips I can think of, and nothing works at all.

Thanks in advance for any help!
