The Input and Output option is not showing up for the slicer morph extension

Dear all,
I downloaded the slicer morph extension to use the _rec.log file for the reconstruction.
however, the input and output option did not show up on my program and I was unable to use the log file.
I tried redownloading the extension as well, but it did not worked.
Can anyone explane to me why this may have happened?

Any advice would be appreciated.

I cannot reproduce this with today’s preview, all three subcategories are there. How did you install the SlicerMorph extension?
Try uninstalling and reinstalling the extension and see if that fixes?
