Cassette install problem with SRAM PG-1170

As my title says, I have a SRAM cassette on my Neo 2T, with the provider spacer installed under it (otherwise there was no way to tighten the lockring) and after a couple weeks use

it seems that the various cogs on the cassette are loose anyhow. You can easily rotate the different cogs in opposite directions from each other maybe five degrees. I've never seen anything like this. Do SRAM cassettes work with this trainer?
