I get the breakpoints logic is that if a certain point is enabled, the width between the previous smaller breakpoint and the certain breakpoint is effective.
Most combinations all work except for settings whose lower end is tablet and at least laptop or desktop is enabled, like this.
When only the tablet point is enabled, it works correctly. Only 480px - 768px effective.
But when it extends to laptop, 480px - 768px becomes disabled at all. Only 768px - 992px is working. Only when I extend the lower end to mobile, like this, then 0 - 992px all work correctly. So we cannot enable the 768px - 992px without enabling 768px below.
