Subject line is too short for complete description, here goes: two new channels started showing in fw5.4 (e.g. 5.4.2522 on #3500) in ECP channel list:
<app id="31012" version="1.4.5">Movies and TV Shows</app>
<app id="31863" version="1.0.23">Roku Home News</app>
But they can't be started necessarily - if the feature was chosen to be hidden (Settings / Home screen), then selecting them in remote app does nothing. It's a confusing user experience. Also they show in somewhat random place in the /query/apps list (could be on top or in the middle) - but not at all in main-screen "My Channels" and as such cannot be re-ordered. Probably did not mean to show those 2 channels in the list at all - IMHO only channels that can be started should be there.
Cosmetic issue but worth a look for the sake of UX consistency.
