Hi Suzie,
Ok, so you can try the following values (keep everything else like it is)
Min power level of MS=19
Increase uplink level=15
Decrease uplink level=25
that should help reducing the UL Interference. Regarding the DL, your settings are already quite good. You could try this :
Decrease downlink level=30
But I can’t be sure that it will enhance your network.
