This is not an issue of field_group, but an issue with the implementation of the toggle. If this is still the case, I suggest you create a core issue.
According to #1276908: Administrative tables are too wide for smaller screens → , [t]he 'Show all columns' toggle is smart enough to show only when there are hidden columns. However, as soon as I place a view field → in a Details field group, the smartness disappears and the "Show all columns" toggle always shows up.
Before:
After:
Clicking on the toggle has no effect as all of the columns are already there, except for making it go away (but it shouldn't be there in the first place).
Closed: works as designed
