I am using WINE on linux, but i don't think that's the problem.
The only way i fixed it is to open the full chr and save two 4k version that i can import each separately with "import background" and then "import sprites" in NAW as if i open a full 8kb chr there is no way i can switch between them, tried everything, i feel dumb :)
Oh my, I really need to learn how to use itch better. There was no reply notification to this!
I'm glad you found the solution! Yes, currently only 4KB or smaller CHR is supported in NAW. If you open a bigger one like you tried it will trim the rest and only open the initial 4KB of data.
In the future there will be a CHR manager which will allow better handling of this type of data inside a project. It'll be absolutely necessary for many features such as actor animations and screen raster effects. The CHR loader and manager is partly implemented already, just not present in the public version yet.
edit: I see there's a subscribe button, I guess that should do it :)
