CDR incomming shows ringroup instead of extension

When I look in de CDR reports, I see when incoming call goes to ringgroup 600 en extension 201 picks it up from the ringroup, the cdr shows a conversation between incoming cid and the ringroup 600 instead of extension 201.
When I hover the mouse in the cdr over the ringroup 600 nummer, than I see Channel 201 in the popup.

I readed that I could make a call-log-table.php file in /etc/asterisk directory, but it does not change anything in my freepbx 2.11

I want to see the extension wich is picking up the call instead of the ringroup.

any advice?
Thanx in advance

Hi, I’m on the same boat here, has this function been somehow disabled?
