Hello,
First of all, bonus fields is a great extension ! Love it !
However, there is a issue with PivotX 2.3.6 and Bonus Fields 1.31 extension. When the entry page is loaded in the admin, the bonus fields slider checkbox appears for a few seconds and then disappears. Because it appears only during loading, on a faster system this might be as well unoticed.
Anyone have any ideea on why such a bihavior is occuring?
