I have done a default installation of Magento 2.2.5 CE and when I click on an order in the Magento Admin I get the following error:

“Order View. Information changes have been made to this section that have not been saved. This tab contains invalid data. Please resolve this before saving”.

The problem is that I haven’t done any messing with the back end code and its a default install. Where am I going wrong? There doesn’t seem to be any other error messages. (I haven’t turned on developer mode). When I go into the Module Manger there are no modules listed so I don’t think its that. I don’t have any extension installed.

I’m baffled. Any help greatly appreciated.
