Office365 Sharepoint Site showig wrong Publishing Date?

Hi All,

I create maybe 5 or 6 Microsoft Teams last week (8th June 2017) but every Teams sharepoint site is showing with a publishing date of 18th May 2017?

All of these sites were create via Microsoft Teams and some (NOT ALL) actually have had 2 sites created?

Example

https://xxxxxxx.sharepoint.com/sites/Intl-IT

and

https://xxxxxxx.sharepoint.com/sites/Intl-IT2

The first has all the stuff I'd expect in it (Docs etc.) the second has nothing except the same number of memeber etc and if you click on conversations etc. you'll end up in the first site.

Any ideas please?

Cheers

Simon
