Uhh, yes, I had this appear (rather "not appear") as well.

Don't know about the fourth row, but when I copied one of my toons to Tribble (it used to be there, I deleted it and recopied to see the STF drops conversion), keys were no longer displayed on the 2 trays I have set (as well as the boff tray).

As seen in these pics:

Kinda hard not to loose track of your powers.
