At the 19 second mark on your video you have a toggle for “Show Column”
That toggle is not created by ACF, that toggle is created by some other plugin. I do not know what other plugin that is. There are a couple of 3rd party plugins that have this feature. Those plugins are not created by or maintained by the developers of ACF.
You have to figure out what plugin it is that is providing this feature and you need to contact support for that plugin. The issue is in that plugin.
