Image Volume Not in the Box

[xwghua]

Last few weeks, I updated my ImageJ, and then the ClearVolume plugin got an error related to the function "Views.flatIterable()". Then I saw there was an update on Feb. 17th for the plugin. The good news is now the ClearVolume window can be opened, but the bad news is the image volume appears only as a 2D projection in the entire area, no matter how I alter the 3D box. Please instruct how to fix the problem, or maybe update the plugin. Many thanks!
