Playmodes? menua after end or automatically play next video?

how do I  change Playmodes/understand playmode icons ?

When playing from a network drive, sometimes at the end of a video the player returns to the menu of videos,  other times it automatically play next video.   I must be changing the setting by accident, but I could use some help figuring out how to change it back manually. one way ot another… I have found the playmode menue and one mode has no Icon, one is a “loop(1)”    and the other is a “loop”  but can’t figure out what each mode means…

any help would be apreciated, thanx
