Ahhh, now I understand.
That red flag totally confused me.
Thanks for clearing this up for me and sorry for the inconvenience.

In my balance the amount I sent is missing.

Both Addresses are in my Wallet, see my screen:

Hi,
I wanted to send all my BTC to one address. The app propted me, that I'm sending to my own address. I did so 4 days ago. The transaction is completed and verified 680 times. But it's "red" and not in my wallet. I tried refreshing the app and account. nothing happening...

Here is the transaction: https://blockchain.info/tx/5e9bc91c6b003cce4820c1677ea790c28da06704edca4c56dfb3d8227df7934e
