A channel playlist offers separate stations or titles to choose from. An HLS manifest describes how a player retrieves one media presentation, including its renditions or sequential segments. Both may use M3U-style text, but a channel import screen and a media playback screen do not necessarily expect the same kind of list.
Identify what each entry represents
A list containing News, Sport and Culture is organized around viewer choices. A manifest containing many short numbered media pieces is organized around delivery. Opening the latter as though every segment were a separate channel produces confusing results.
Use the intended input screen
A direct media URL may belong in a playback action rather than a whole-account import. A service can provide a channel list whose entries lead to HLS manifests. That layering is normal; the player follows the appropriate resource at each stage.
Do not flatten the delivery manifest
Saving or merging individual HLS segment lines into a personal channel list usually loses timing and update context. Keep the supplied top-level stream address rather than treating temporary segment URLs as permanent stations.

An example to work through
A list of ten television stations is a navigation resource. A list of ten four-second media pieces can represent only forty seconds of one station.
