How do I delete my Instagram account from my mobile?

I already deleted my Instagram account via my laptop. It is still displayed on my mobile phone. If one clicks on the top of the screen on his user name one shows his whole accounts and if I press there on the account, which I already deleted on my laptop, I do not come in logically into the account.

as I said we still see this account. If any of you know how to fix it, I would be happy to hear from you

Had the problem more often. Somewhere you can manage your accounts, but do not know exactly how. Otherwise just delete the app and reinstall it should be gone

OK
