A take can sometimes contain multiple files. This happens e.g. if a graded clip follows an initial proxy. When navigating by day, scene or shot, Oropod lists one row per take, with one or more files in each.
Oropod treats two files as the same take when their metadata gives both of them the same scene, shot, take and camera.
A (a menu symbol next to the filename) marks a row containing more than one file.

The row shows the newest of its files that Oropod can play, so the still frame and the filename you see belong to that file. The rest are still there behind it.
Open the row, and the same symbol appears next to the filename, this time as a button. Tap/click it to list the take’s files, newest first, each with the time it last changed. A tick marks the file you are watching. In a project drawing on more than one source, every file also names the source it came from.

Your selection remains for as long as you stay on that take. Move on to the previous or next take and you get that take’s own newest file again.
Oropod never groups files that have no take number, so each one gets its own row.
This is helpful e.g. when receiving clips from a shooting day before the script supervisor’s report. When scene, shot and take numbers arrive, Oropod updates and groups files automatically.

Merging happens only where you browse by take. Folders under Sources, Tags, Playlists and search results each list every file on its own, so a take with two files appears twice there.
