Problems with channel names

#1
Hi good day. I want to know why when I load an iptv list with 2 channels with the same name but with different urls, it only shows me one of them. for example:
# EXTM3U
#EXTINF: -1, vh1
http: // xxxxxxxx
#EXTINF: -1, vh1
http: // yyyyyyyy
Only the first one appears.
I must change the name of the second option so that the two channels appear in the list.
# EXTM3U
#EXTINF: -1, vh1
http: // xxxxxxxx
#EXTINF: -1, vh1 opc 2
http: // yyyyyyyy
There is some configuration or something that you must activate or deactivate to avoid changing the name.
Thank you in advance for your help!
regards!
