DS JR, DSD 64, 128 and Roon

When I run DSD 128 via Roon through DS Jr, Roon converts to PCM and down converts to 176khz. Is this correct functionality? I was thinking DS Jr. handles DSD 128. Or maybe this query should go to Roon?

DSD 64 via Roon through DS Jr work fine - outputting DSD 64.

If you are using USB it should. But if you are using the bridge it does not. The bridge only handles DSD64.
