I am new with bitcoin and I need some help from experienced members.

I have a server with bitcoin core where we accept some payments and use bitcoin core as mercant.

The problem is that we have got an incoming transaction which we didn't see in our wallet.

Here is the hash of the transaction: 460c0dc70ef52fd66142d1798a1735b4613c9ffec478efe5997d1ede0d16f28a

In our bitcoin core through the bitcoin-cli command line I can see the following:

bitcoin-cli listtransactions 1K7Pci1re92vQuTSXbirmvQsmYMpXHQWbQ
[
  {
    "account": "1K7Pci1re92vQuTSXbirmvQsmYMpXHQWbQ",
    "address": "1K7Pci1re92vQuTSXbirmvQsmYMpXHQWbQ",
    "category": "receive",
    "amount": 7.02278014,

  }, 
  {
    "account": "1K7Pci1re92vQuTSXbirmvQsmYMpXHQWbQ",
    "category": "move",
    "time": 1463303102,
    "amount": -0.00007000,
    "otheraccount": "1M1LTHjc1JAcVfCoyhSkoP1VH8B9RLY8tg",

  }, 
  {
    "account": "1K7Pci1re92vQuTSXbirmvQsmYMpXHQWbQ",
    "category": "move",
    "time": 1463303102,
    "amount": -7.02278014,
    "otheraccount": "1LBa3bAVF5RSfnFnm3sX1Zm5R8WU1J8xnK",
    "comment": "invoice forward"
  }
]

As I see funds were successfully moved to 1LBa3bAVF5RSfnFnm3sX1Zm5R8WU1J8xnK, which is correct, but on blockchain, for example, if I go here https://blockchain.info/address/1K7Pci1re92vQuTSXbirmvQsmYMpXHQWbQ I see that were sent to another address!

How to understand that, and how to find where these bitcoins have gone?

Any help will be appreciated, thank you very much!
