Denafrips Terminator II NOS/OS issues

Hello all,

On my T-2 DAC, I follow instructions with the T-Plus or T-15 manuals (there never was a T-2 Manual) to first press Mute, then press Mode to set OS, I am able to achieve the correct LED Lamps lit, but then after a number of seconds the LED Lamps will change and then only read 44.1 and 1X.

According to the Manuals, 1X LED on 8X LED on = Slow Filter, 1X LED off, 8X LED on Sharp Filter.

I thought I was doing something wrong, but this does appear to be a fault with my unit.  I have earlier written to Denafrips for further explanation.

I can also simply press the NOS/OS Button, and that LED will turn on-off accordingly, but have no further adjustability, and again all I see is 44x1 and 1X LEDs lit.

Thank you for any help-advice you may provide me
