Using the 'All with Info' option doesn't seem to return more than Critical findings. I moved $CurrentStartOffset = 0 inside the foreach loop to get this far. When it tries to filter for Info objects, the server returns a 500 error. Does this function correctly for you?
Returns 0-4 severity level information.

.SYNOPSIS
Retrieves all vulnerabilities that are Critical, High, Medium, or Low in Tenable.
.DESCRIPTION
This function provides a way to retrieve all vulnerabilities in Tenable that are Critical, High,
Medium, or Low.
Revision 0.1, Sept 2019, jwmoss
Revision 0.2, Nov 2019, aarong1234
.INPUTS
None
.PARAMETER Severity
Option for any of "Critical", "High", "Medium", "Low", "All", "All with Info". Defaults to "Critical","High". All with Info will get ALL vuln data
.PARAMETER MaxRecords
Option for maximum records (rows of data) that should be requested (as a throttle), Default is 0 (all records) [note: sorted by score, descending]
.PARAMETER Detailed
Option to enable detailed data. Defaults to Summary Data. To determine how detailed the resulting data is by querying Tenable.sc "Vulnerability Summary" versus "Vulnerability Detail"
.OUTPUTS
PSCustomObject
.NOTES
None
.EXAMPLE
Get-PSTenableSeverity -Severity "Critical"
Retrieves all critical vulnerabilities, Summary Data [sorted by vprscore (note:Very OLD plugins dont have a VPR Scores)]
.EXAMPLE
Get-PSTenableSeverity -Detailed
Retrieves all critical and high vulnerabilities, Detailed Data (return Tenable.sc Vulnerability Detail data instead of summary) [sorted by vprscore (note:Very OLD plugins dont have a VPR Scores)]
.EXAMPLE
Get-PSTenableSeverity -Severity "High","Medium" -Maxrecords 200
Retrieves high and medium vulnerabilities, up to 200 records, Summary Data [sorted by vprscore (note:Very OLD plugins dont have a VPR Scores)]
.EXAMPLE
Get-PSTenableSeverity -Severity "All" -Detailed
Retrieves all non-info vulnerabilities, Detailed data [sorted by vprscore (note:Very OLD plugins dont have a VPR Scores)]
