All Emails purged after running Compliance command except those in "top of information store" Folder

Hello Tech Folks,

We have received a request to delete some items(Email Messages] from EXCHANGE.

According to this guide, 

 https://docs.microsoft.com/en-us/microsoft-365/compliance/search-for-and-delete-messages-in-your-org... I created my content search and ran it [ STEP1]

Then as STEP2: I  connected to Compliance & Security Center in PowerShell as Admin, and ran New-ComplianceSearchAction -SearchName "ABC_004_22_2" -Purge -PurgeType SoftDelete
[ I ran this command atleast 10 times ]

Once I get the status via:

Get-ComplianceSearchAction  -Identity 'ABC_004_22_2_Purge' | Format-list

It shows the task has been completed...
