Every time I click on my screen while using a controller it glitches out

I use a bluetoothed controller to play on Minecraft so I use both the screen and the controller. I was typing in chat with my fingers (you can’t type with a controller), and it let me type but not release the message. When I tried to get out of the chat screen I could for a split second, but then it put me back on it even though I had said to get out of it. I tried multiple times and nothing worked. So since I couldn’t even get out of the chat screen I had to exit out of Minecraft. So I tried again, but this time, when it actually let me out of the chat screen, it had the pocket edition controls up (I was using the controller though!) and I could move but not get to the exit screen, mine, or place. A little bit later it did it again when I was writing with a book and quill. This had never happened before the update.
