Invoice Receipts Holds Alert - Email Problem

Our Invoice Receipts Holds Alert quit working after we upgraded from 11.5.9 to 11.5.10.  Now the alert will not send unless you hardcode an email address into the To: Field.  Also, all the other fields are blank such as  &Vendor, &Requestor, &Amount, &Inv, etc.  Below is our code.  Any idea what is wrong?

SELECT
hrea1.email_address
,hrea1.FIRST_NAME||' '||hrea1.middle_name||' '||hrea1.last_name requestor_name
,hrea.FIRST_NAME||' '||hrea.middle_name||' '||hrea.last_name buyer_name
,u.location_code
,h.ORGANIZATION_code
,to_char(substr(rpad(pol.line_num,20,' '),1,15)) line_num
