When changing templates on custom block the content gets deleted from the DB - concrete5-5.7

Question

I have a custom block for Concrete5 I built which uses multiple template files associated with it. If I apply the template to the block when I am initially adding the block to the page everything works fine. However if I then try to change templates after the block has already been set I run into issues. When saving changes with the new template, all my content gets deleted from the DB; so everything in that current row equals null except the block id "bID", the bID will change to the next increment.
I do not know why this happens!! I feel like I ran into a similar a long time ago but don't remember how it was resolved. Any advice would be great!
My template files are just standard html in a php file with the <?php defined('C5_EXECUTE') or die("Access Denied."); ?> at the top of the file.
My controller (which is my suspect for the issue right now) look like this:
<?php
namespace Concrete\Package\ThemeCaboodle\Block\GridBlock;
use Concrete\Core\Block\BlockController;

use Page;

I apologize for the pretty long file in advance ;) i just want to make sure you can see all possible issues

Answer 1

I think your problem is that in the duplicate function, once you got your results back from your select you put an ENTRY_ prefix everywhere like in $row['ENTRY_thumbnailFID'] when it should really be $row['thumbnailFID'] according to your screenshot
