New-CosmosDbCollection cmdlet parameter AutoscaleThroughput parameter doesn't allow values lower than 4000

Issue

PS version: 5.1.22621.4249
Host: ISE, Visual Studio Code
OS: Windows 11, ADO latest Windows-2022 agent image
CosmosDB PS module v5.0.0.

Running New-CosmosDB collection with AutoscaleThroughput parameter with value 1000 results in the following error:

$Parameters = @{
Id = 'ScheduleSettings';
Context = (New-CosmosDbContext -Account 'xxx' -Database 'DocumentDatabase' -Key ([SecureString]::new()) );
DefaultTimeToLive = -1;
IndexingPolicy = (New-CosmosDbCollectionIndexingPolicy -IndexingMode 'Consistent' -Automatic $True <# Paths omitted #>);
PartitionKey = 'id';
AutoscaleThroughput = 1000;
Database = 'DocumentDatabase';
}

CosmosDB\New-CosmosDbCollection @parameters

ERROR: New-CosmosDbCollection : Cannot validate argument on parameter 'AutoscaleThroughput'. The 1000 argument is less than the minimum allowed range of 4000. Supply an argument that is greater than or equal
to 4000 and then try the command again.

If I update the value to 4000 it creates collection successfully, I can then lower it in the Azure Portal to 1000 successfully.
I can create collection in Azure Portal with autoscalethroughput 1000 without any problems as well.
Why is the 4000 min limit on the PS cmdlet? Can you please advise? Thank you.
