Groups/Categories for channel list not showing

Hello. I'm using a Channel List and Guide url from my IPTV provider. When i use the same list on a different app, it shows channels in different groups/categories instead of putting 1000's of channels in the one All Channels group. For example, there should be a USA TV, USA Locals, various countries, Sports, etc. Any idea how I can get my channel list to appear like this in ProgTV for Android? I've tried it on a FireTV and a Fire Tablet and both have the same issue. All Channels are grouped in the one main All Channels group. I'm not sure if there is a way for me to add the group names to the URL. I didn't have to do it for the other app. I just used the urls below and it worked.

Thanks in advance for any help.

I've tried different variations of the url below. ... s&type=m3u ... utput=m3u8 ... s&type=m3u
