EOS still showing in MyEtherWallet while it was transferred to an exchange.

Hi all,

My EOS tokens are still showing up in MyEtherWallet while I transferred (and sold) them quite some time ago.

Is there any reason why these tokens are still showing up in MyEtherWallet? Everything seemed to have gone right with the transfer. I received the EOS tokens and was able to sell them. I just don't know why they are still showing up in MyEtherWallet. Is it because they were originally registered there?

Any ideas why this might be happening? Your input would really help me out as I'm trying to empty MyEtherWallet and just want to be sure I'm not missing something.
