Time Reverse layer
There is a persisting bug with the 'Time reverse layer' command - often drops first frame, sometimes drops or displays random wrong frame elsewhere in the reversed layer.
Thank you for filing this bug report.
Can you please post a project file with footage that demonstrates this issue? Post a link to your files here, or if you prefer not to post publicly you can send it to firstname.lastname@example.org. (If you send to that address: A) Do not send .zip files, they will be blocked; renaming to .thisisazipfile is OK. B) Post a comment here when you have sent the email. I need to manually check that inbox.)
