I am creating the .net.xml file for sumo simulation. After creating, I save it to a Geojson file and use kepler.pl to visualize it, but the road occurs many disconnections. Is there anything wrong with my CFG file parameters. Here is my CFG file parameters:

<input>
    <osm-files value=".osm"/>
    <type-files value=".typ.xml"/>
</input>

<output>
    <output-file value=".net.xml"/>
    <plain-output-prefix value="osm_net_demo"/>
    <output.street-names value="false"/>
    <output.original-names value="true"/>
</output>

<projection>
    <proj.utm value="true"/>
    <proj.plain-geo value="true"/>
</projection>

<processing>
    <geometry.remove value="true"/>
    <geometry.remove.min-length value="250"/>
    <roundabouts.guess value="true"/>
    <ramps.guess value="true"/>
    <edges.join value="true"/>
</processing>

<tls_building>
    <tls.discard-loaded value="false"/>
    <tls.discard-simple value="true"/>
    <tls.guess value="false"/>
    <tls.guess.joining value="true"/>
    <tls.join value="true"/>
    <tls.uncontrolled-within value="true"/>
    <tls.ignore-internal-junction-jam value="true"/>
    <tls.guess-signals value="true"/>
    <tls.yellow.time value="1"/>
    <tls.default-type value="actuated"/>
</tls_building>

<edge_removal>
    <keep-edges.components value="1"/>
    <remove-edges.isolated value="true"/>
</edge_removal>

<junctions>
    <no-internal-links value="true"/>
    <junctions.join-turns value="true"/>
    <junctions.join value="true"/>
</junctions>

<report>
    <verbose value="true"/>
    <xml-validation value="never"/>
    <aggregate-warnings value="5"/>
</report>

The first network is mine, the second network is from another paper:

How can I eliminate the disconnections?
