update illustrator adding white boxes around many objects

I'm a teacher in a lab and my new updated Illustrator isn't working as it should. Every time I draw something, it creates a white box around the objects. Also, when students turn their projects in, the preview is correct, but when I open it on my machine it has the dang boxes. ALSO...their color is vibrant and mine is greyed down. I have the color settings to sRGB as always and then we use CMYK on our printable work. I've never seen such discrepanices before. Tech will want to know that I've troubleshooted first, but I'm coming up with nothing. It's not a bounding box issue, which is all I get off of Google over and over. Preview photo and my view attached. (note the paw prints). The colors are the same here because they're both on my computer. That's a different issue I'll work on later.
