Pre-Release 5 Text Box Error

Text will not show up

I was typing commands into the interface and when I hit Enter I noticed that the text box showed up, but the text was completely missing. I'm not sure if this has happened to any other players in this Pre-Release, but it is very unusual. Nothing shows up, just the text box itself. I am able to see what I am typing, but as soon as I press Enter the text is gone but the box around it still remains.
Here is an example of it from a screenshot I took.

P.S. Great job on 1.14! It is one of my favorite updates so far!
