It doesn't display the tree properly, no case visible

The tree was fully visible when I first time try it.

This is some weird thing it keeps doing sometimes although I explicitly set the min width of the columns. Drag the splitter left of the header of the Duration column to the right to widen the Name column.

Thanks, I should notice that.
