Scarlett Solo buffer set to 64 is changed to *120* by JK

[TProch]

Using a Focusrite Scarlett Solo and Focusrite usb driver. Working great with JK. The gear latency and jitter is very low. BUT I am trying to reduce the interface buffer size to 64. I have read that it can help reduce internet latency, which is still too high?? Focusrite Control app lets me do this and it sticks, but JK switches it to *120* when I load the audio profile into JK. Anyone else seeing this? Anyone know the fix, or if this is in fact normal/ok?

Sample rate: 48000
Bitrate: 320kb/s
Audio frame size: 2.5ms
Network packet rate: 400pkt/s
Buffer size:*120*
