JPEG Issue in Siril

I’ve been using Siril for a couple of months. Still learning. This is my first post on Pixls.us. Has anyone run into this issue before: When I’m done stacking and processing an image in Siril, and I save the result to a .JPG file, I get two lines of diagonal green blocks in the resulting file, about 5-10% of the time. It doesn’t happen with any other file format, just .JPG.

Apologies is this has been discussed, I tried to search this forum but couldn’t find a relevant topic that discussed this issue.

I posted an image of the problem here:

Hello.
We need the FITS image for trying to reproduce the bug.

Thank you.
