Point 35 is correctly in the gpx file, as a shaping point, why the Zumo shows this as a flag, I dare not say.
Point 35 in the BC GPX file:
</rtept>
<rtept lat="38.721981095150113" lon="-121.224045753479">
<time>2025-02-13T07:38:26Z</time>

<sym>Flag, Blue</sym>
<extensions>
<trp:ShapingPoint />
gpxx:RoutePointExtension
gpxx:Subclass000000000000FFFFFFFFFFFFFFFFFFFFFFFFFF</gpxx:Subclass>
</gpxx:RoutePointExtension>
</extensions>
</rtept>
Point 35 in the MRA GPX file:
<rtept lat="38.721981115079" lon="-121.22404575348">
<name>4306 Old Auburn Rd, Granite Bay, CA 95746-6489, United States</name>
<extensions>trp:ShapingPoint/</extensions>
</rtept>
You can see that MRA uses fewer options than BC to compose the GPX file, but that can't be the reason that point 35 is shown as a flag in the Zumo.
I would create a support ticket via the website, so that the developers can look into this.
