Flamingo render isocurve issue

Hi all,

I have recently been having trouble with the final rendered image in flamingo.

I have isocurves turned off as well as all other options (see image 1 below). However once I press stop on the render the isocurves come out and destroy the image (image 2 before stopping the render and image 3 after). I did not have this issue last time I used flamingo and to my knowledge I have not made any changes (besides trying to fix the issue).

Could something of changed during an update? Any suggestions would be appreciated.

Image 1 - Settings

Image 2 - Before stopping the render

Image 3 - After pressing stop and the image being finalised
