I have noticed that my virtual seed tray keeps on blinking. Every few seconds it will blink. Any ideas?

Also, I reread the area that explained what the colors were, but I have at least one plant that is not matching up. One of the yellow spots has a red circle around it and it says that I have already found it. I though the yellows were the ones that I can get but have not found yet. I know that it is not one of the plants that I am currently growing. Could you please explain this to me?

Thank you.
God Bless.
