Problem with the percentage sign in the text box

Hello everyone, I've been experiencing a strange problem in Photoshop since yesterday. When I create a text box and try to write something like "100% cashmere," the % sign automatically moves to the left of the 100, resulting in "%100." Even when I copy-paste "100%" from Notepad, the % sign still moves before the 100. It's baffling! I have the latest version of Photoshop, and I'm on PC.

In my screenshot, it's also strange because when I place my cursor just after the % sign and try to delete it, I can't. It's as if this action is blocked.

Thanks you all of us
