Note 1: If the issue is not reproducible on the first try please switch between "Strict" and "Custom" radio buttons and try again to open the drop-downs from the Custom section. (See the video attachment (made on win7) ).
Note 2: The position of the drop-downs apparently is broken just on windows 7. On win 10 the position of the drop-down is correct but on every switch between standard, strict and custom radio buttons the page behaves like a refresh.(See the second attachment (made on win10) ).
The issue is not reproducible on Release 70 or Beta 71.

Note 2: The wrong position of the drop-downs apparently is easier to reproduce on windows 7, on win10 the drop-downs position just sometimes is wrong but every switch between standard, strict and custom radio buttons the page behaves like a refresh.(See the second attachment (made on win10) ).
The issue is not reproducible on Release 70 or Beta 71.
