Why are tags copied to the end with LiveStyle and Hayaku?

Question

Sublime Text

Has anyone come across such a glitch: I use livestyle and Hayaku, I start editing CSS in the editor, the code is copied, pasted at the very end of the file and the content of the written style is highlighted. If you write something else, it is copied again, pasted at the end, and so on ad infinitum. Sometimes it even inserts the code to the devil understand where. When you delete a copy of the code, the main code is also deleted.
