After I create a formula using the Latex editor, I copy it and paste it into another multiple choice answer and slightly adjust the answer. This worked fine for a while, but now, whenever I paste, Latex generates 2 of the formula. When it happened before, I thought I was accidentally hitting CTRL-V twice. I was able to simply delete the extra formula.
Now Latex does not allow me to edit it, freezes, and kicks me back to the initial edit screen for the quiz. I lose anything not yet saved on the question and the entire quiz if I hadn't saved it yet.
Why is this happening and how can I avoid it?
