I never use proxy clips, almost always source clips, and very occasionally
transcode problematic clips.

I think you need a workaround for that problem with the checkbox being
ignored, but I do not know anything about the proxy mode in Kdenlive. Maybe
there is a way to modify the xml and render it with melt.

comes from libavformat. It appears very frequently in many tools (too
verbose), is related to determining the duration of a clip, and is not
likely related to your problem.
