Hi, I did same too. Still shows unverified.

When i tried to withdraw XVG from Electrum wallet and deposit into exchange - the transaction was successfull.

In other forums I read that this is a known bug which they may be trying to fix or will fix during next release. The forum link as below, hope this helps.

The test withdrawal transaction from exchange to Electrum wallet that I conducted, is still showing unverified. I am not going to worry about it now, seems like working both way withdrawal from exchange to electrum and deposit from electrum to exchange successfully.
