Transfer 1.6 - Rename feature only working on Digitakt

Elektron Software Transfer
#1

I can use the new right-click Rename feature on Digitakt files (Sounds, Projects, Samples) but not on Digitone or Analog Keys (Sounds, Projects). Is that expected?

#2

are they factory content or your own sounds/projects.
are they write protected ?

#3

My own sounds, not protected
