This tiny little arrow in my Shape tool...

Hello!

I don't know how I ended up with this tiny little arrow appearing when I select my Shape Tool, but it's messing up all my shapes (ellipse, rectangle, etc.).

This arrow normally appears when adding text to a path, which I did earlier, but now it just won't go away.

I've already tried closing and reopening Illustrator, but the issue persists.

Does anyone know how to fix this?

Thanks in advance!
