Can't name sessions

Using TeamViewer 15.4.4445 for macOS Catalina, I can create session codes for quick support, but I can't seem to name them.

I can name the sessions if I go to the TeamViewer web-interface, and the name then appears correctly when I open the macOS app.

When I enter a name for the session code, it allows me to fill the text box field, but then if I hit enter or click outside the box, the field clears.

Is anyone else having this problem?
