You will need to add that field in category form so as to show it. Create an xml file on path: app/code/Vendor/Module/view/adminhtml/ui_component/category_form.xml

Add below code in category_form:

<field name="name-of-you-custom-field">
<argument name="data" xsi:type="array">
    <item name="config" xsi:type="array">
        <item name="sortOrder" xsi:type="number">10</item>
        <item name="dataType" xsi:type="string">boolean</item>
        <item name="formElement" xsi:type="string">checkbox</item>
        <item name="source" xsi:type="string">category</item>
        <item name="prefer" xsi:type="string">toggle</item>
        <item name="label" xsi:type="string" translate="true">Label of the field</item>
        <item name="valueMap" xsi:type="array">
            <item name="true" xsi:type="string">1</item>
            <item name="false" xsi:type="string">0</item>
        </item>
        <item name="validation" xsi:type="array">
            <item name="required-entry" xsi:type="boolean">false</item>
        </item>
        <item name="default" xsi:type="string">1</item>
    </item>
</argument>

This kind of issue is the normal case when we do the data migration and especially when we have a custom category attribute in the m1.

When you do data migration the data is already transferred to the m2 database but the m2 code structure is obviously diff from m1 so we need extra effort to add the UI component in the custom module.

I.e you have Navision id in the database of m2 as varchar which migrated from m1 but not showing in the backend.
