Attendance - Maintain List of Attenders

[Ladybug]

I'm using Ver 8.5 and trying to do a maintenance of the "Maintain List Of Attenders" on the current list. On the first attempt, I can use the sliding bar to scroll down the list, then I delete one member from the list. Subsequently, I am not able to use the sliding bar to scroll down, I had to use the mouse and scroll down using the arrow down icon. Besides that, the page keeps returning to the top after deletion of a member. It is a pain in the neck having to do this all the time, I hope your development team can fix this "bug".

Thanks.
