Where do you see group 5 (which button)? The current ghost should be for those in group 5. If you are in group 1 like me, it would only come in a few hours.
Any idea when was the last time you find ghost? I pinged my friend for ghost so can use timestamp when messages were sent to check.
If you lost track of your ghost time, keeps checking every 5h at the time given in "I have multiple farms". One of them should be the right one.
