It looks like these are just a few spurious fibres. If you’re after a specific bundle (as your screenshot suggests), you can just add a few exclusion regions to get rid of these.
Unless of course everything you’re showing there is what you’re referring to as the looping fibres. In that case, you’ll need to provide some more context to allow people to give you advice… it’s quite hard to see what structure you’re showing there… Maybe add an anatomical volume for reference, or show the situation from a few different angles.
In general though: spurious fibres are never unexpected. In fact, Maxime Descoteaux recently showed, based on extensive data from a tractography challenge, that up to 70% of all bundles generated are typically entirely false positives (I’m talking entire bundles here, not just a few spurious streamlines). With that as a context, I wouldn’t worry about a few spurious streamlines… as long as there’s only a few compared to millions of streamlines in your connectome as a whole.
