Post Preview showing "null" then text follows. plx help

[SeverityGaming]

Hey everyone, I don't know what mods could be causing this (below is a list), but whenever I click preview when writing a post there is a preceding "null" right before the actual post text (see image below). It only comes up when previewing the post, after posting it does not display. What file might I look in to remove this.
