Click "Use" on the entries you want to use, which in most cases will be the top one with the best accuracy for ADS and Scope respectively. Alternatively you can use the best match that uses the same setting for both ADS and Scope, but that will result in the accuracy being worse.
The reason is that 45 for Aim and 35 for ADS is completely different, so you are probably better off just setting Aim to the same value as General Sensitivity, and only use 35 for ADS in your conversion.
FOV 102 on 3440x1440 is the closest match for the vertical FOV if you want to match FOV 95 on 1728x1080. If you take into account the monitor sizes you will get sensitivity values that are a lot slower, this is to compensate for the increased monitor size and essentially keep the 24.5" portion in the middle of the 34" monitor the same as the source. If this feels good or not is down to your personal preference, but I would try without monitor sizes first. Also note that you need to use another method for hipfire than 360 distance if you do this.
This is about as close as you can get, but set the Aim Sensitivity to 25 rather than 16:
