I was not able to reproduce this.
Can you try to edit that file and see if this changes anything - '...\Modules\VMware.VimAutomation.Common\12.7.0.20067789\net45\VMware.VimAutomation.Common.ps1'?
(use the location from where you load the module from).
For example make it empty first and see if that changes anything - if it does, try to remove sections of it until you find what is making the difference.
