Ropieee and i2s DAC ( Suptronics X4000)

Hi, just purchased this DAC since it is inexpensive and has an ess9018K2M chip. I have it setup as an i2S DAC in ropieee and it works and sounds great. However, I am unable to play DSD material without Roon converting to PCM. In the setup screen, DSD64 is in yellow which means the format is supported and also, using another player (moode), I can play DSD64. Any ideas? Thanks!
