None of the prior releases had this issue with the stereo 2.0 track.
EDIT: I just double-checked the stereo track on this recent release of Fright Night and found no issues.
This is the fourth time I have reviewed this title on disc (TT, TT re-issue, Sony BD, and now Sony UHD). The Sony UHD, from what I've been able to research, ports nearly everything from the 2017 Eureka import, plus several new items.
