Members field gone from Settings / Display Styles / Catalog fields

What happened to this field ? It does show up when you look at the work or library page for the book, but it is no longer available apparently as a catalog field that can be used with the Your Books display. I KNOW it used to be there. It is a really really useful field, much more important than the Rating field that seems to have replaced it.

Any ideas ?

>1 cns1000: There never was a field AFAIK. Members with that book can be seen on the far right, where links for edit, reviews, delete etc. are

I still see it under the other icons on the right where it always was. A bust sillouette with a number.

Ah I see ! Never mind, I figured it out. I had the Power Edit button selected and when you do that, the check box hides the Members field. At least on my setting.

Just one more reason not to leave power edit on.
