That's weird! I have every version of PSE from 6 thru 13. Hate moving on from version 6 because I knew it so well, but wanted the upgrades in the newer versions. I currently have 11 and 13 loaded on my desktop. I found version 13 to have some "glitchiness" such as you are describing. I would apply a style and could see it in the layers pannel, but it would not show up on the layout until I moved my mouse over the layout in different directions. Finally, it would pop on there so I could see it. It still acts like that, and I have not found a fix as yet. Am thinking I need to totally uninstall it and re-install it to see if that fixes some of the glitches I am observing. Version 11 has a very small interface which makes reading things on a large screen very hard, so I liked that the interface of version 13 was much larger for a person like me with glasses, but the glitchiness in 13 has made me resort back to using version 11 most of the time. Plus, 11 still has the magic wand which I love. Hope they eventually put that back in the newer versions! If you find the solution, please post it here so I will see it.
