Loss of Punch in punch out icon

All of a sudden I don't seem to have my Punch In/Out icon in my toolbar.9sonat 8.5 Studio).

I checked Views/Toolbar, and it is not an option, only the Loop/Punch one is, which is there.

Not quite sure what to check.

Did I accidentally select a particular function somewhere along the way and eliminate it?

Thanks.

I went to transport to check it out. The Loop option doesn't mention punch in/out at all. The record options does, I checked off "overwrite" and checked "punch recording" but it didn't make a difference to the icon in the record toolbar. It still only has the loop function.

Can you answer this question, as I can't remember, does you record toolbar have only 2 icons in total, or 4? ( if it has 4, 2 would be for punch in/out, 2 for looping? or only 2? Mine only shows the 2, and I can't get it to show any options other than looping.
This is really frustrating as this is obviously an integral part of the recording process.
