Voucher codes are not generated

Hello.

I faced some trouble.

While implementing marketing I've activated CRM_LOY_PROD

And made these settings

• MarketingMarketing Planning and Campaign ManagementCouponsDefine Voucher Code Variants
• MarketingMarketing Planning and Campaign ManagementCampaign ExecutionDefine Number Range Intervals for Voucher Codes
• MarketingMarketing Planning and Campaign ManagementCampaign ExecutionBusiness Add-InsBAdI: Convert Voucher Code to Alphanumeric Form

Now I try to generate 5 voucher codes (Code type: Unique Code) using the Anonymous Voucher campaign.

Vouchers are generated. I can find it using search but it has no codes. In the generated attachment I have data like this:

Can anybody give a hint what I made wrong?

Thanks in advance.
