This has never happened before and I don't know why it did. I've tried everything to find these.  In Track mode I'm missing a display of these: Input, Output, Volume, Gain, Pan & Sends. The only thing that's showing is Clips.  Other Projects display these but for some reason this one project doesn't.  I don't know if inadvertently pressed something to have these disappear. I've searched all over to get these displayed again but to no avail.  Can anyone help? Thanks.

Try changing the value in the Track Control drop down

SHIFT+left and right arrow step through the values

so simple-dee di dee! The only button I didn't check. Thanks!

Did you try expanding the size of the track header , drag it to the right or down or both. . You should see all the boxes then.
