How to plot two channels or more on the same graph?

Thanks a lot.

I tried to edit the experiment "Acceleration with g" by loading it from "Load experiment" button in editor. Not changing anything yet. I loaded the experiment via QR code and found all 4 waveforms in MULTI of the same color-orange. This is different from the built-in experiment on smarphone under Raw Sensors>Acceleration with g in which I can see different colors.

The section of MULTI is extracted below:
        <view label="Multi">
            <graph editor:uuid="160" label="Acceleration" aspectRatio="2.5" style="lines" lineWidth="1" color="ff7e22" partialUpdate="true" history="1" labelX="t" labelY="a" labelZ="" unitX="s" unitY="m/s²" unitZ="" logX="false" logY="false" logZ="false" xPrecision="3" yPrecision="3" zPrecision="3" scaleMinX="auto" scaleMaxX="auto" scaleMinY="auto" scaleMaxY="auto" scaleMinZ="auto" scaleMaxZ="auto" minX="0" maxX="0" minY="0" maxY="0" minZ="0" maxZ="0"  mapWidth="0"       >
                <input axis="x">acc_time</input>
                <input axis="y">accX</input>
                <input axis="x">acc_time</input>
                <input axis="y">accY</input>
                <input axis="x">acc_time</input>
                <input axis="y">accZ</input>
                <input axis="x">acc_time</input>
                <input axis="y">acc</input>
            <value editor:uuid="161" label="Accelerometer x" size="2" precision="2" scientific="false" unit="m/s²" factor="1" color="green">
            <value editor:uuid="162" label="Accelerometer y" size="2" precision="2" scientific="false" unit="m/s²" factor="1" color="blue">
            <value editor:uuid="163" label="Accelerometer z" size="2" precision="2" scientific="false" unit="m/s²" factor="1" color="yellow">
            <value editor:uuid="164" label="Absolute acceleration" size="2" precision="2" scientific="false" unit="m/s²" factor="1" color="white">

This section supposed to display 4 waves of different color, right? When I load this experiment to my phone, all four waveforms of orange (see photo attached). Why is that?

The complete phyphox file is also included for reference.
