I tried out the wordswap feature. Highlighted some text and then clicked wordswap. It then a popup told me I needed to set up an AI model. Firstly, my AI models were set up and work fine with chat and rephrase, so that might be a bug itself. However, the actual bug I'm reporting is that when I hit cancel on the popup, the Apply-Discard popup text persisted on the screen and no amount of clicking on the popup or outside of it would make it go away. I had to completely close the tab and load NC back up. It only repeated that once since then, so it may just be a me problem (it happened on an Asus Chromebook).
