Anomaly with sliced/printed model

I have an OPXL dual extruder. Latest firmware and PS software (Version 2.7.0+MacOS-arm64)

When I print with PETG .32 quality I get a surface anomaly as a line (gouge) on the model. I looked at the sliced layers and find a 'break' in the layer at least 3 different areas. Hoping someone can enlighten me about what they might represent. I created the model in Shapr3D.

RE: Anomaly with sliced/printed model

Those are the Seam locations for different areas of the print. Or the start and stop for that particular run of the extruder. You can control the location in the slicing software.

RE:

Thanks for the info. I've seen the location vs random seam setting, but I've not had a problem with seams in the past...only with this model. Is there a setting that controls the seam overlap/fill rate? When it prints, there is an actual split in the model that will crack. In other words, the seam is not welded together as I have seen most of the time. Generally when I see a seam it has extra material on the surface that I need to sand down a bit.

Here's a picture of the bad seam on this model:

And here's an example of a reasonably good seam:

Before I start horsing around with extrusion and retractions and such I'm going to try the painting method (new to me) and manually locate the seam to an area that I hope will be less problematic.
