Bundle not enrolling users in courses

Hi, we were wondering if you have any idea what went wrong.

When we created a bundle on Hikashop, users are not enrolled in the bundled courses after buying the bundle from the shop. The same courses when sold individually, enrols them automatically as it should.

Only thing I can think of is a wrong category in Hikashop (ie: product not in the Joomdle category). Double check that first.
Also, check that order is being confirmed in Hikashop.
If individual course purchases are working (enrolment is happening) I cannot think of any reason for bundles not to work.
