Cannot delete income account!

I’ve created a Prepaid Account under income, I stopped using it and I would like to delete permanently. I have modified every cash sale that was related to the account and it’s now back to zero. But somehow Manager still does not let me delete it.

Here’s a video for more clarity:

Those cash receipts are obviously somehow linked to income account.

If you like, send me your backup file to and I can have a look further.

I was able to delete the account by duplicating the transaction in each cash receipt and deleting the first one which makes no sense since they’re exactly the same. anw, problem solved. thanks for your help.
