Can not create custom Detailing symbols in Connect

Detailing symbols are working fine in V8i . Trying to get them to work in Connect.  When I go to create them I keep getting and error message

The pull down to attach the cell under the Tail wing  populates with nothing from my cell library.

I have these set in my standards.cfg file

MS_DETAILINGSYMBOLS_CELLLIST = $(_USTN_ORGANIZATION)dgnlib/DrawComp/*.cel
MS_DGNLIBLIST_DETAILINGSYMBOLSTYLES = $(_USTN_ORGANIZATION)dgnlib/DrawComp/WWE_DETAILING_SYMBOLS.dgnlib
