email – Microsoft Outlook hiding text after pressing enter

When typing an email, the previous line of text is hidden after pressing enter. Then, the cursor is stuck and can’t be moved.

I’ve checked if it’s deleting the text and it’s not, since when sending the email to a different email, you receive the hidden text as well. I’ve scoured the internet for solutions for this and it’s not Overtype, line breaks, or formatting issues. It does not occur on other applications, only the Outlook app. I’ve also tried repairing the application and that did not work.

I am using Outlook as part of Microsoft Office 365. It is the newest version and my computer is running Windows 10.
