Things have been working fine w/ the remote and wall switch until now. The wall switch is a dimmer switch with a red indicator light. The remote will not turn on the light or the fan and when I push the green light button on the wall switch, the fan will sometimes come on (not supposed to control the fan). The red indicator light on the wall switch is fading in and out when I push the green light button. This is only happening in one bedroom. Anyone know how I can fix this issue?

Check to be sure the switch is properly wired. Try changing the frequency of the switch and receiver. If that doesn't work you may need a new switch.
