Having issues with QOS RT-AC3100

So I have a few questions about QOS on this AC3100 router. I have TWC and I have the max speeds that TWC offers which are 300 down and 20 up.

Now if I use Adaptive QOS, my speeds are fine they are shown in the first picture.

If I use Traditional QOS my speeds are very low and you will see this in the second picture.

Is there a way to correct this or this is how it is? I am on ASUS FW 9.0.0.4.380_2697.

After I upgraded to this FW I did reset router.

Thanks in advance.
