[Text Area] Not working properly - Unity 2019.3 Lighweight

Hey everyone,
The [TextArea(X,Y)] code is not working for me, displaying an empty block without the writeable string.

[TextArea(4,4)]
public string sentence;

The images speak for themselves: It appears that the Text Area IS THERE, but I can’t click nor write on it.

Also, the Text Mesh Pro and vanilla Text components both seem to also be bugged. (Basically anything string related.)

Any help is appreciated, thank you!

Please submit a bug-report as described in this document:

It’s important that you report these issues together with a reproduction project if you want them to get fixed. If you don’t do it, it might be a long time until someone else reports them or until Unity Technologies find them.

After you submitted the bug-report, you receive a confirmation email with a bug-report Case number. Please post the Case number (number only, not the link) in this forum thread for Unity staff to pick up.

I’ve seen this affecting other asset store assets too.
On my own stuff, I had to set “fixedHeight” to 0 when creating a style based that was using TextArea as base.
