Error Loading Tokens and Maps

The token and maps images I have imported aren't loading properly. They load when I am zoomed in to the maximum amount but if i zoom out they begin to be replaced with random images from other webpages I'm on. I tried changing my internet connection. It only started occurring after I purchased an asset pack. How do I fix this?

Can you please follow Steps 1-3 of our Solving Technical Issues wiki page, taking special care to temporarily disable all browser add-ons and extensions, temporarily pause your anti-virus, and try switching browsers (for Chrome/Firefox specific issues) to see if one of those components is causing the problem. If all of that fails, please follow Step 4 , including providing all of the necessary information, so that we can further assist you.
