When creating a duplicate support it is locked on Z axis

[IchBin]

I tried using this software yesterday for the first time. I noticed that if I create a support, and then try to duplicate that support, that the duplicate support is locked on the Z axis. Even if I check and uncheck the lock model option. There's no way to move it on the Z axis that I can see without deleting it and just creating a new support. It moves up but snaps back to the build plate.

I'm using Cura 4.9.1 and custom supports 0.1.0.
