An issue on sliding when more then 1 images are defined but only 1 is active

The issue description.
The one image it is displayed all the time (it is defined without any date limit).
Other images are defined, switched to "ON" and they have defined range of date when to be shown.
There is a case when slideshow does not work as expected.
It is the status where additional images are defined, but none of it should be displayed at specific moment.
The slider then shows: 1th image, 1st image, empty slide.
Expected behavior is that only one picture is shown without any image sliding.

Example of settings:

I have seen the problem but I don't know for now how to solve it
may be that there is a conflict with one option (loop), but by definition a slideshow is not designed to show 1 image ...
I have to test by my side if I can reproduce the issue. Does it occur the same if you disable the slide on OFF instead of using dates ?

As I wrote. Most of the time there is only one picture shown.
But we would like to announce some activities a year few day before.
And because I want to prepare these pictures before, so I set the date interval for them.

I found workaround that is not ideal. To duplicate the first slide, and set time to 0 ms.
Unfortunately this makes sliding one picture.


The best solution I can imagine is to fix code of Slideshow CK to work correctly also in described case.

I don't know what happened, but now I watch the problem also for one defined image only.
It could happen in the past that I didn't notice when I defined only one picture.

I would expect the complement to such behavior that if only one image is active, there will be no attempt to slide it.
