Toggle in table block

I use the table block for a Timetable. Each row has a toggle field. As far as i understand, i can not edit the content inline, which is fine. But what i realized with the toggle is that i can switch it directly in the preview, but as soon as i save the page it changes back to the toggle-setting from before.

Is there a way to prevent the possibility to toggle inline, or what would even be better to make it save the toggle-setting?

I guess this is related to a bug with the toggle field in table layout in general.
