will not let me meld

I must reach 120. I placed 2 x K plus a wild 2 for = 40
in my hand, I have 4 x J = 40
2 x 9 plus another wild 2 + 40
plus 1 x 7 and 1 x A
It allowed me to place the K's on the board but it will not let me place the j and 9 up. What am I doing wrong or not seeing? Just started playing
