I can't find anything on the net re SirusXM Bypass mode, and I've never seen a Bypass Mode indiction on any other Roku app.
After removing a channel, best practice is to clear the Roku's memory by restarting it before reinstalling the channel. Did you do this? Without the restart you may not get a clean reinstall.
Depending on your Roku model and Roku version number you'll find the System restart option under either Settings > System or Settings > System > Power ... or just unplug from its power source for a few seconds then plug back in.
