I am using this code to create a multi-select category option in a form.
It saves the data in the table correctly but when I try to edit it, it shows the selected category name in the field but doesn't show a checkbox(checked) in the drop down list. Instead It shows the Default Category box checked.

 <field name="category_id">
 <argument name="data" xsi:type="array">
 <item name="options" xsi:type="object">MagentoCatalogUiComponentProductFormCategoriesOptions</item>
 <item name="config" xsi:type="array">
 <item name="label" xsi:type="string" translate="true">Category</item>
 <item name="componentType" xsi:type="string">field</item>
 <item name="formElement" xsi:type="string">select</item>
 <item name="component" xsi:type="string">Magento_Catalog/js/components/new-category</item>
 <item name="elementTmpl" xsi:type="string">ui/grid/filters/elements/ui-select</item>
 <item name="dataScope" xsi:type="string">category_id</item>
 <item name="filterOptions" xsi:type="boolean">true</item>
 <item name="showCheckbox" xsi:type="boolean">true</item>
 <item name="disableLabel" xsi:type="boolean">true</item>
 <item name="multiple" xsi:type="boolean">true</item>
 <item name="levelsVisibility" xsi:type="number">1</item>
 <item name="sortOrder" xsi:type="number">30</item>
 <item name="required" xsi:type="boolean">true</item>
 <item name="validation" xsi:type="array">
 <item name="required-entry" xsi:type="boolean">false</item>
 </item>
 <item name="listens" xsi:type="array">
 <item name="$ $.namespace .$ $.namespace :responseData" xsi:type="string">setParsed</item>
 </item>
 </item>
 </argument>
 </field>

Here is the screenshot.

I didn't used Data Provider

 <?php

 $this->collection = $salesCollectionFactory->create();
 $this->dataPersistor = $dataPersistor;
 $this->storeManager = $storeManager;
 parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
 


 public function getData()
 
 if (isset($this->loadedData)) 
 return $this->loadedData;
 
 $items = $this->collection->getItems();

 /** @var MagentoCmsModelBlock $block */
 foreach ($items as $block) 

 $form = $this->loadedData[$block->getId()] = $block->getData();
 $form['category_id']=explode(',',$form['category_id']);
 
 $data = $this->dataPersistor->get('sales');
 if (!empty($data)) 
 $block = $this->collection->getNewEmptyItem();
 $this->loadedData[$block->getId()] = $block->getData();
 $this->dataPersistor->clear('sales');
 else 
 if ($items)
 if ($block->getData('banner') != null)
 $banner[$block->getSaleId()] = $form;
 return $banner;
 
 

 
 return $this->loadedData;
