Thanks for your feedback! There was a conflict between the title of your post and the used steem platform. 'Steempeak有更新啦，好多人期盼的功能出现啦！！！✨' becomes the permlink 'steempeak' (because special character are not allowed in permlinks).

My logic searches for transfers from your account with the permlink in the memo field. steempeak.com contains the word 'steempeak', therefore your last post has been found. I've added a few more tests on the sent value in the memo field and it should work now.
