Hey @bmeyer,
So it seems Slice Machine isn't fully configured to convert older Slice models to the new format needed for Slice Machine, yet.
The workaround that I had to use here was to use the + Create Slice button in the builder to create new Slice that would be configured correctly and build the Slices in the builder and migrate and code from my components in to the new structure. I know this is a real pain especially when you have 17 Slices/components like yourself.
The team is working hard so that this process will be automatic with the above screen in the future, but for now this the only way.
Sorry for the inconvenience and I will check if there is an easier way.
Thanks.
