How to delete or fix Twitter Cards

[Alwarakiblog]

I applied for Twitter Cards and my blog got accepted. I then found out that I used the description, title and image from one of my blog posts. So every time I post a link I get the same Twitter Card showing, which sucks for me.

It seems Twitter Cards are complicated right now, if you can fix my cards from me yourself then I’ll be very grateful. If not, then I’d like to have my Twitter Cards deleted. Thanks.

I am also trying to remove the existing Twitter Card on our account. Can not seem to figure out how to do so. How can I remove them since they still show up with each tweet.
