Strange Ghost image Duplication when using Night Vision on UDL

As title suggests I'm getting this weird issue when using Night Vision toggle on characters - it creates this weird ghost image of the map totally displaced in the shadows, and of tokens as well. Have searched and searched and no answer seems to appear. Here are some images of the problem:   Any help is greatly appreciated, and I understand it is still in experimental stage, but would be cool to know why or how this is happening

Please make any reports on UDL in the main thread, and check the logs you can also provide that might help troubleshooting things: <a href="https://app.roll20.net/forum/post/8422745/a-new-light-bug-thread-updated-dynamic-lighting-and-fog-of-war" rel="nofollow">https://app.roll20.net/forum/post/8422745/a-new-light-bug-thread-updated-dynamic-lighting-and-fog-of-war</a>
