I expect there's every chance this problem is because I am merging views from a v1.0.0 created show file into a brand new v1.0.1 show file as I know there were issues with views in the first release.
Anyway, in case you're not aware of this one...
I started with a new show file v1.0.1. When I merge my views (from a v1.0.0 file) and select "append" they are there. If I select "replace" they show up in the Views bar but do not have the correct content.
I have not had time to see if this works fine when merging and replacing from a v1.0.1 file instead.
