Hello. It's really strange what’s happening to you because it doesn’t happen to me, and no one has reported a similar issue. I honestly don’t understand what could be going on—I don’t know if it’s something related to the operating system, the keyboard language, or something else—but I can't find the reason, and unfortunately, I have no way to replicate it, which makes it really difficult for me to work on something invisible to my eyes.
I have made a medium-sized update to the plugin, releasing version 1.1.0, which includes a new UI that might work better for you. I don’t like it as much as the classic version, but maybe it will work better for you. Try it out and let me know what you think.
