Coupons are juxtaposed (no space between them) in the notification email when bulk coupon is purchased

When users purchase several a bulk coupon on the same order, the module is supposed to send a notification email containing the list of all the coupons created.

This email template is editable in "Conditional Actions", and contain a token supposed to render the coupon list.
The template is available here:yoursite.com/admin/store/ca/uc_coupon_purchase_bulk/edit/actions
This token is: [coupon-bulk-codes]

THE PROBLEM occures when the token is rendered because coupons are juxtaposed, making the user see only one long coupon.

Example: let's say the user ordered 3 coupons: COUPON01, COUPON02 and COUPON03...
The notification email sends: COUPON01COUPON02COUPON03

Would someone has an idea of how to fix this bug ?

This would be of great help !
