Problem with Copy and Paste function, please help!!!
Hello, I just realised something weird happened when I try to use the most basic COPY&PASTE function.
Whenever I tried to copy a shape layer (or anything), the new shape layers seems to be masked inside the original one. (see attached photo)
I did not screw with the default layers setting, so I think there might be a bug inside the software?
I have tried uninstall and install the AE and even reboot my mac. But the problem seems to remain unchanged. Now the AE even crashes when I try to open some old files!

Please does anyone know why? I need to finish my work for my projects. Thank you.
