How to solve the Slide display problem on our Mobile Page ???

Hello.

We contacted you yesterday to ask for your help with the layout of the mobile version of the issues we are reporting.

And here is our concern:

When we try to move our Slide circled in Blue (on this screenshot: https://imgur.com/a/EQ4iWm1) to the “Empty Column” (circled in orange on the same screenshot) just above to fill the gap in this column, the slide is no longer displayed at all as you can see on the following screenshot: https://imgur.com/a/P7FnywX.
How then, to make the Slide appear moved in the “column above” since it disappears immediately after having moved it in this empty column located above ???

But your response was:

Please check what width you have set on the column. Also, you can try to add a row and add the slide in that row.

But we didn’t understand your answer because it doesn’t help us at all. So, can you answer us very explicitly ???

Please try to tell us through a screenshot, how to display the Slide which once moved above in the empty column, does not display at all ???

How, to make the Slide appear moved in the “column above” since it disappears immediately after having moved it in this empty column located above ???

Waiting for your more than urgent and necessary response.

Thank you too.
