For the skill icons in the shortcut HUD - what's your setup to display the icon?
Did you recently update from an earlier version? There've been changes to this in some of the last major updates (I think in 2.29.0), adding a Type selection to shortcut content labels (icon, text or bar content).
For the choice buttons - is your button prefab set up correctly? If no button prefab is selected, ORK will generate an empty game object and add a button component, i.e. there's no real visual element to the button itself.
Is your GUI box used for tootlips (selected in the menu settings) as large as the screen? If that's the case, it might be due to using Secure Drag, in case it's enabled in Game > Game Settings.
