Hi @P T,
Did you mean the Office 365 Current Channel with Version 2304: April 25 get the problem in Word?
If yes, I suggest you refer to this support article: https://learn.microsoft.com/en-us/officeupdates/current-channel
For Word updates:
We fixed an issue where users would see the window flash white when closing an item using Windows High Contrast mode.
- We fixed an issue where the right side of the email body was cut off when printed and in print preview.
I didn't find any updates is related to your problem. You can try to give a feedback to Microsoft about this problem in Word with the update version:
Microsoft values your opinion. Your feedback goes directly to our engineers and helps us shape the future of Microsoft products and services for all our users.
Hope it's hlepful.
