ROON and Bluesound NODE N130

My usage pattern:

(Roon Core on Synology) >—Ethernet—> (Roon Ready Bluesound NODE N130) >—USB—> (FIIO K9 Pro) >—RCA—>(ATOLL IN 200 SIGN)

I use Bluesound NODE N130 with USB DAC FIIO K9Pro AK4499EQ (32bit/384kHz). When I play music through ROON, I view in ROON Option in N130 Roon Ready limitation (24bit/192kHz). How can i fix this?
