Some form fields are not preserved through the preview/edit process
Selected values of the select list with multiple choices allowed are lost.
Documenting Kyle's observation that clicking "Preview" on an entry resets some of the fields.
It seems to be the Selector/Multiple type that has this problem.
There are 4 screenshots:
1) the New Entry page showing form being filled, with "Type of Expertise Required" and "Method of Contact" set.
2) preview showing these set.
3) the active New Entry page after the preview, showing the fields have been reset
4) the next preview, showing these fields are empty.
