Sometimes your browser may store old data on a page. This might result in previous button icons looking out of place or not working or simply an overall odd or inconsistent visual.
You can clear all your browser cookies and cache in your browser options/settings. But if you would just like to do it for a single page, try one of these:

In most Windows and Linux browsers:

• Hold down Ctrl and press F5.

In Apple Safari:

• Hold down ⇧ Shift and click the Reload toolbar button.

In Chrome and Firefox for Mac:

• Hold down both ⌘ Cmd+⇧ Shift and press R.

This will reload the page and its elements to the latest version, eliminating compatibility issues. Please also note that Internet Explorer and Edge are not supported at this time, but Microsoft's upcoming use of Chromium may change that.
