I have a mymonero web wallet that has some moneros in it I recently downloaded the new GUI wallet and sent some monero to it from exchanges. The other day I went to the web wallet but I put in my seed from the GUI by mistake. Not really knowing what I was doing I imported the GUI wallet into the web wallet. The GUI wallet still has the same amount that I put in it,but it shows up in the web wallet when I type that seed into it as well. When I type the original seed from the original web wallet the proper amount shows up for my first wallet.
How do I delete the web wallet with GUI seed?
Is it necessary? Does this impose any kind of security risk?
