Powershell, design manager, uploading html file not creating associated master page file

I am uploading a xyz.html file through powershell for 2 site collections, when .html file is uploaded and published it automatically creates xyz.master file. It is working fine for first site collection only, for second site collection .html file is uploaded successfully but it is not creating associated .master file. If I close powershell console and run again it works successfully.

I have ensured .html is checked in and publish properly, If I manually unpublish and publish .html file it creates .mater file. What could be the issue?
