Is number of Air Actions for an app limited?

While adding support for S-Pen’s Air Actions to an application, I have noticed that no matter how many actions I define in remote_actions.xml, only the first 10 are displayed in the drop-down menu in the S-Pen settings. However, there is no limit mentioned in the available documentation. Is this by design, or am I doing something wrong?

In my case, 8 remote actions are displayed. I think as there are total 8 remote actions (button and gestures), settings shows the actions for these 8 gestures.
