Dont like the Random features that pop up

When I reply to emails, randomly I get a pop up to select a different signature. It should be based off which email address Im composing an email in. Its annoying to have to constantly close this box. Also quick reply of "Thanks" popped up randomly as I was scrolling through an email and my thumb hit it. The Undo button didnt work so now I sent out a quick thank you to someone by accident. Its completely embarrassing. Ive never seen that feature before and it has never showed up again. I now look like an idiot sending an email that says "Thanks for your reply!" for no reason. For this embarrassing gaffe I give Spark 1 star.
