Garden Plot not locking

I am having the same problem.  I have all 10 plants (not all colors, but all types), all of them planted, all fully grown  every space full with some kind of plant, but the terminal and last plot will not open up.  I am on a New Game+ and didn't have the last plant during my first play-through.  Side note, my fish tank is stuck at "cleaner" even though I have all the fish.  Again I got the last 2 fish in New Game+, but the tank was pristine before without the last 2.
