I'm not sure what to search for to solve this one. I have a scope/persistence of data issue, where a variable used to populate my data structure is over-writing other items in the data structure (ImageFileName). This is my code:

})
} #if not true
} #foreach row $resultHelp
##note: $image gets inserted in the spreadsheet later, but since the names aren't showing correctly when use $results, I'm not sharing that part.
I can see after this runs for the 9 rows, that each ImageFileName is the same in $result. How do I do this so it maintains what is returned from the method? Right now I am trying New-Object, but it didn't fix the issue.
This is what $resultHelp looks like:
[0] $true (I'm not sure why it puts true at the top) [1] @(HelpCode=9;ScreenNumber=1;TextID=HELP_...JA;PictureID=HELP_...RIB) [2] @(HelpCode=9;ScreenNumber=2;TextID=HELP_...ROLL;PictureID=HELP_...ROLL) [3] @(HelpCode=9;ScreenNumber=3;TextID=HELP_...EDGE;PictureID=HELP_...UT) ...
I am using Powershell 5.1 and VSCode.
Update:
I checked again, and in Get-ImageName, it's returning a file name like "Contact_Service"...bmp and it looks like it's getting put in the psObject ImageFileName...($imageNamePath), and the same thing for the other images found. When I look in the end, $result has all the same values for that ImageFileName. and the one that used to say "Contact_Service"..bmp is something else now, matching the other ones in $result.
Update2:
There are a couple errors:
New-Object : A constructor was not found. Cannot find an appropriate constructor for type System.Drawing.Image
and
New-Object : A constructor was not found. Cannot find an appropriate constructor for type System.String.
for where I tried dealing with the object over-write issue in the main code
Update3:
After I get the psobject in good shape, I put it in a spreadsheet with Export-Excel. I just wanted to give this info so you know why I'm putting it in the psobject like that:
$xlsx = $result | Export-Excel -Path $outFilePath -WorksheetName $errCode -Autosize -AutoFilter -FreezeTopRow -BoldTopRow -PassThru # -ClearSheet can't ClearSheet every time or it clears previous data
