I just found some bugs.
1) Picture in Picture : When you add this FX, you're supposed to be able to see the handles to skew the clip. But mine doesn't show any handles. So, I can't adjust it at all. Please refer the screenshot below:
2) Mesh Warp : The same issue with above. Although I increased the grid size, it doesn't show me any handle.
3) Titles & Text : Title09 has an issue that the letters are disappeared if you change it.
