Can't see channel Newsmax 1115 in channel list on LG TV

So I can view Newsmax channel 1115 via my Xfinity X1 box on my LG television just fine, but I cannot see the channel listed in the list of channels on the TV. I have to type in the channel number to view the station. The channel is listed in the channel list accessed via the Xfinity remote, but is absent from the list accessed by the LG remote. The weird thing is that the adjacent channels below 1114 and above 1117 are present, but not 1115. How do I get my TV to list this channel? I prefer using the LG remote, so that's why I'm asking.
