Highlight caret line is missing alpha/opacity value

I'm using codelite with dark background color - and have set caret line highlight to bright yellow.
The result is nowhere near bright yellow - it looks more like a very dark green - diffucult to spot from the background.

PS: I believe (seem to remember) that the caret line highlight once had an aplha/opacity value ???

Seen with codelite 6.1 and 7.0 on ArchLinux
