An error can occur where some Action Pro-Studio icons turn into Coffee Cups. The tools will still work, but they don't display correctly. This is the default icon if Corel can't find the proper icon for any reason.
To fix this issue, go to:
C:\Users\UserName\AppData\Roaming\Corel\CorelDRAW Graphics Suite X8\Draw\Workspace
Reset the workspace within CorelDRAW, then close and restart CorelDRAW.
The icons should be copied back into the appropriate location from CorelDRAW's original icons path.
