Empty CDR report

We are using cdr_adaptive_odbc.conf to save CDR in database asteriskcdrdb .We have checked database and it show CDR value being stored in asteriskcdrdb.cdr table.

But when we use Freepbx GUI to see CDR report, it does not show any output. We are using cdr_adaptive_odbc.so. cdr_adaptive_odbc.conf is as under:
connection = asteriskcdrdb
table = cdr
alias start => calldate
alias Host => Host
alias myvariable => myvariable

cdr show status
