Coupon dokan

Hi

I wanted to export the coupons claimed according to each vendor so that i can reimburse to the vendor. However, when i export it, the vendor name changes back to the admin store name once exported to excel. As shown in the pic. Is there any way to work around this because before exported, in the table, it is showing the correct vendor name. It should be Jason611, but it is showing begolfpro in the excel once exported.
