Cannot Delete or Change a model in Visual Composer-Locked

Hi Guys,

I was creating a model in Visual Composer and due to the system slow down, I logged off while I am working on the model.

Now when I logged in again i get the screen saying do you want to open the model as Read Only. when I go to Manage Models and try to delete it I cannot as it says Failed to Delete the model, is Locked by the User.

I am doing this without any model open in the window still I cant. Can somebody please help me how to delete the model?

It also says cannot delete because the model has been opened by another user with same user name whereas I am the only user working on it.

Thank you.
