Adding Video Markers in Dorico

An odd thing I noticed after trying out a few different videos synced to a flow in Dorico. Anytime you add a marker with either the plus sign or shortcut, the timecode for the marker always seems to be set at 1 frame less than what the timecode in the video is showing for that frame. For example, I stop the video on frame 01:00:16:08 and add a marker, it sets the marker to 01:00:16:07. Sometimes you can change it manually, and sometimes it won’t let you.

Anyone ever notice this before?
