Helpdesk Pro - Articles Missing Category ID in Knowledge Base View

Hello,
I am experiencing an issue with the Knowledge Base Categories view in Helpdesk Pro.

I attempted to see if ChatGPT and I could narrow this down, but was unable to pinpoint the issue, so Im here hoping you guys can address this.

Im receiving the following server error. It appears to be giving ONE error for EVERY article that is displayed on the page. So if there are 15 articles, then it will throw 15 errors.

[STDERR] PHP Warning:  Undefined property: stdClass::$category_id in /home/xxxxx/public_html/xxxxx/components/com_helpdeskpro/View/Categories/tmpl/default.php on line 57\nIssue Details:

• The articles display correctly under their assigned categories, but the 
  Code:

  category_id
   is missing from the retrieved article data.
• We checked the database, and every article has a valid 
  Code:

  category_id
   in 
  Code:

  #__helpdeskpro_articles
  .
• The query used to fetch articles appears to join 
  Code:

  #__helpdeskpro_categories
   correctly, but 
  Code:

  category_id
   is not being assigned to the article object.
• This results in articles being displayed under "No Category" on the frontend.

Troubleshooting Steps Taken:

• Verified that all articles have an assigned 
  Code:

  category_id
   in the database.
• Printed debug output of the 
  Code:

  $article
   object in 
  Code:

  default.php
   → 
  Code:

  category_id
   is missing.
• Reviewed 
  Code:

  Model/Articles.php
   to confirm the SQL query retrieves 
  Code:

  category_id
  .
• Tried modifying the query in 
  Code:

  Articles.php
   to explicitly select 
  Code:

  tbl.category_id
  , but no change.
• Checked 
  Code:

  Model/Categories.php
   for how 
  Code:

  $item->articles
   is assigned → appears to be missing 
  Code:

  category_id
  .

Expected Behavior:Each article should retain and display its category ID so it appears under the correct category in the frontend when we do the debug, but it doesn't.Request:Please review how articles are fetched and assigned in the Knowledge Base view and advise on a fix.Site Details:

• Joomla Version: 5.2.3
• Helpdesk Pro Version: 6.0.3
• PHP Version: 8.3

Thank you!Adina
