Help on MS365 Business Std license issue

Hi Community - 

Issue with MS365 Business Standard license

I have a ms365 biz standard subscription/license attached to my email (email address removed for privacy reasons) - Australian subscription. I am global admin to the account. 

It expired on 5/9/26. I bought a new one on 5/9/26 from a office supplies store (Officeworks, a large chain in Australia)

I took help of MS telephone support to add the new product key. so far so good.

However, it appears that the new subscription's license is not attaching to my id. under my id, 

• Under 'Your Products' - it is showing both the expired subscription; and the new subscription. 
• Under the 'Licenses' - it is showing MS 365 Biz Standard - 'Available licenses - 1' and 'Assigned licenses - 1/2'  - if i click on MS 365 Biz Std - it tells me - 'Licenses - 2 purchased' - under Assigned Licenses - 1 ; and under its drop down - 'user's name' - 'Type' -> 'user' / Assigned licenses - blank / email - user's email. 
• Under 'active users' -> my id -> 'licenses and apps' - it is showing MS 365 Biz Std - check - and 1 of 2 licenses available. 
  
  After much engagement with MS telephone support; I am assured that everything that needs to be done has been done; the expired subscription will simply disappear after a time; and licenses has been properly applied. We did much poking around over Quick Assist - including unassign / assign license. 
  
  However, the fact that that the account continues to show an expired subscription and active subscription at the same time; and the fact that there seems to be one license still available (there should technically be no extra license available - as old has expired and new one should be in use) is kinda bothering me. 
  
  This is an id for my business, and I am naturally concerned of any abrupt disruption / data loss etc. 
  
  Can someone please help to clarify / give suggestions that whether all is well, and i should have a peaceful sleep, as MS tele support suggests; or is there a cause for concern?

Kind regards
