Check is printed twice when I run F110

I am running F110 and the check file is printed twice. I have already done the below checks and the settings looks fine to me. The major issue here

We have already checked the following options:

1) Do not void any checks in variant settings

2) Output attributes of check file copy (No. of copies 1)

3) Uncchecked the check file copy option in the variant and given for printing but it still prints twice.

Also in the spool request I see there is only one check file.

Please help on how to avoid printing two checks.

Thanks
