Auto sell and Unsealed Spellbook

For the selling bug, It has only happened to me like 2-3 times and I don't know what is causing it, but sometimes when i back to buy an item i somehow sell one of my items I had without pressing the sell button, and I dont realize till I leave base because I only bought an item. At first I thought it was me just being stupid, however i recently saw a pokimane video and at the start it happened to her. https://www.youtube.com/watch?v=HzlfGDWKiBQ

On the unsealed spellbook bug if you swap a spell for smite it doesn't display how much damage the smite does until you use it at least once.
