While your transaction may have been cancelled by whatever system you used, you have to wait for it to cancel out everywhere else too. 

Since you only provided a destination wallet and not the actual transaction ID, it's hard to provide much info. I do, however, see transactions going to the wallet you specified above without issue. It does look like your fee (8.93 sat/B on a 224byte trans) was well below a reasonable fee to be processed in a decent amount of time on the transactions that show up though.. 

I suggest leveraging https://bitcoinfees.21.co/ to ensure your transactions process in a decent amount of time in the future. Relying on a cancellation is unreliable.

To see your transaction ids, check the following links

you will notice the transaction IDs under the heading "transactions"
