3&4 and 5&6 channels have a low cut! Please help!

I am using UR44 and the rest of the 1 and 2 channels have a low cut. 3-4 and 5-6.
I tried on my DAW also I tried direct but it still the same.
I uninstall the drivers and installed them again and still the same.
I also tried on my laptop and it stills the same.

I have been trying to solve this problem for 3 days and checked all around the internet but I could not find any solution.
If anyone can help me with this issue I would be so happy While we are all staying at home.
I am looking forward to getting some help
