Is this a computer error or an empire error?

In the hand below you will see that after raising with pocket kings and getting called in two places the bb pushed for another t35. The action was then to me and you will see that I only called the t35 rather than pushing over the top to push out A,x. However, Empire did not let me do that. The screen only offered 2 buttons: the fold and call. Anyone know why this happened?
