Message time to live setting for Queue/Topics

Hello All,

Whenever I create Queue/Topic using powershell Script, "Message TTL" value just gets sets to default rather that as per script. So

after all queue/topic are created then I have to manually go to settings on Portal to update the queue/topic TTL property.

Script link :: 

Can someone advise if there is something I could update in the script so I could avoid manual work or is there any other workaround....

Thanks!!
