Prime keyboard missing the language layout change button (android keyboard)

[idanidan]

Since the jelly bean update my TF201 is missing the language layout change button in the stock android keyboard (not the asus one...)
The long pressing on the space key isn't working as well.

I have checked 2 languages in the list of the input languages of the keyboard and set the Android English keyboard to default.

Any suggestions?

Found the little "unseen" icon in the notification area... is there any way to get the language button back to the keyboard?
