Hello again,
Sorry about this, thank you for the image.
From the image, this usually occurs when you either have a trial office on your device or maybe the present office on your device is corrupt.
Since you are using office 365, may I ask do you have other office applications on your device?
Go to Control Panel > Programs > Uninstall a program and remove any other office on your device expect for Microsoft Office 365 apps.
Reboot your device, then run a repair on the office application: Repair office
- Right Click on Start > Select Installed Apps or Apps and Features
- Scroll down until you see Microsoft 365 Apps
- Click the three buttons beside the Microsoft 365 Apps
- Select Modify
- Click Online Repair (this will take a while to be done)
- Restart the device

You can also decide to remove all the office apps on your device and then download and reinstall the office apps.
