"There have been reports on problems with addresses without public key on the blockchain - If you add the address to an empty wallet using the private key option, they should be resolved."

Known issues:"
I read something somewhere about this exact problem. I believe you just need to send BTC from that address so it is known. I could be wrong, and I cant remember where I read it.
Good luck
Thank you for your help! I've tested both options. They both resolve the problem.
Would be a good idea to either fix this or offer an error message which contains a remark on these possible solutions.
