Make sure you have marked : selling = enable selling, Publishing = Publish product directly. And for active those settings please navigate to Users->All Users->Edit Seller(For whom the problem is appearing) and let me know the result.
I have created a subscription pack named “Subscription Test” and I have added 9 products into that package. I did not find any inconsistency. Can you please let me know the name of the subscription package which you are facing in trouble when uploading product.
