"Overflow" ??

In the wee hours of this morning I was trying to get my Airplay to work again.  I have the older silver AppleTV and an iPhone 5 and iPad Air.  I was pushing this and that and getting tired so I went to bed.  Today I went back to trying to get Airplay to work.  I restarted the AppleTV and it came up to "Overflow".  I don't know what I did but it continually just opens to this.

What do I need to do to get the Main Menu back with all of the drop downs?
