Trouble with lntermediate layers

I’m having trouble using intermediate layers. I think I have them set up correctly but they’re screwing up interpolation of instances that I don’t think they should affect. The glyph I’m working on is £. Here’s a screenshot.

It is a bit tricky to understand if I don’t know the master coordinates. And the compressed has only three weights. That might cause problems.

I sent the file on December 9 if you want to take a look at it. I sent it to support, not to you directly.
