Hi,
There seems to be a bug with fill between slices tool in the nightly version 4.11.0-2019-03-26. It was also in the nightly 3 days before that.
The problem is the interpolated labelmap is inverted :
To replicate this, just try to use the tool with any volume. (I’ve tested this with MRHead)

Hi Roozbeh,
Sorry for the late reply. I tried to reproduce it, and indeed, the Fill between slices effect does this reliably.
We’ll fix this asap. Thanks for the report!
