Right, so that Visualize Grid looks different than your first screenshot of what you want it to be. So just move the slots so that they match that first screenshot and it should be fine?
Probably whats also confusing you is the fact that Windows 10 puts artificial gaps between adjacent windows. In fact, on Windows 10, those gaps exist because the borders of the windows are in those areas, but the borders are merely invisible. You can confirm that by simply opening a few windows, any windows, and right clicking an empty space on the windows taskbar, and then clicking "Show windows side-by-side". You will see that Windows itself also shows those gaps.
But that doesn't even matter. Just click Visualize Grid and move the slots so that they match what you want in the first screenshot, which has some overlap
