Why does the homework question template repeat after previewing?

[Saitama]

I don't know why anyone never posted about this thing and this has been a bug(not sure what should i call it) from long.
Whenever i post a question in the homework question, i always preview it once but the template gets repeated after the whole post. I always manually remove it. While previewing the post, the template repeats below the post in the "Message" field.

This has been talked about before.
