Have you tried opening your account in a private window? We need to check if this is caused by an underlying browser problem.
Private browsing will not save any data in the cache making it a great place to check for browser problems. You can use any of these keyboard shortcuts to launch a private window on different browsers:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox: press Ctrl + Shift + P
Safari: press Command + Shift + N
Access your account from there and check your transactions. If it works fine, go back to regular browsing then clear the browser's cache.
