Executing XMLA with AMO PowerShell does not create measures - powershell

Question

I wrote a PowerShell script to automate deployment of SSAS Cubes. I use the Deployment Wizard to generate an XMLA file and then PowerShell AMO command to deploy it. However, when I run it the tabular database gets created but all measures are missing. Running the same XMLA from SQL Management Studio or using Invoke-ASCmd produce the correct database with all measures in it. Am I missing an option or something in the "Invoke" command?
