As madshi mentioned, currently madVR doesn't support moving multiple subtitle lines independently of each other. If one line gets flagged as unmovable on-screen, madVR won't move any lines until the unmovable line ends, and a new movable line starts. I noticed this behavior as well before releasing this update, but we figured it'd be better to release now for the SRT fix and have madshi fix the ASS quirk with mixed movable/unmovable lines at a later date.
XySubFilter is currently set rather conservatively, with both Soft & Hard Positioned tags flagged as unmovable to ensure typesetting doesn't break.
