Content-Length is update even "Update Content-Length" option is unchecked

In the repeater, Content-Length header is update even the "Update Content-Length" option is unchecked, I found this when I follow the lab "HTTP request smuggling". When check with the Logger show that Content-Length is changed. example ### In Repeater tab: Content-Length: 4 (- which is I intent to) In Logger tab: Content-Length: 20 (- which is updated to correct content-length even the option is unchecked) Check with Intruder tab, this option seem to work correctly.

Hi Sukon, Do you have any extensions installed and loaded when you observe this behaviour?
