MagicMirror: Zoom-Error

Hi, I have some issues with the zoom-function in the config.txt. I set the zoom for testing to a value of 0.7 like this:

zoom: 0.7, After this i wanted to set it back with deleting the code-line but nothing happened. I tried to reset it with: zoom: 1.0, but nothing changes. It doesnt even mather if the number is 0 or 100, the size of everything stays the same. My problem now is that the zoom worked for me the one time I used it first. But I can’t get it back to normal size. It is like the problem that icekuhn mentioned in the last post here: https://forum.magicmirror.builders/topic/1521/zoom-scaling
