Creating seamless transitions between two lofts

I am trying to make a helmet and I thought it was done, but when I exported it into blender for texturizing I noticed that the two main lofts I made for the helmet are not joined smoothly and there's a crease. I think it may be related, but there's also a gap in the two halves of the helmet on one side after I mirror the model. I covered the top of the helmet with a mohawk so that part is not a big deal but I think it has something to do with why the lofts are not joining smoothly. I made the spline handles parallel on the curves I used as guides to make the lofts already, but they are not joining smoothly still.
I suspect there is some kind of start profile condition that will smooth it out, but I don't understand those and I tried a few times with no success. I've added a picture of the gap at the top of the helmet and also the seam at the crown of the helmet that creates a halo around the top of the head.

Without access to your doc, its hard to say what needs to be changed. but the easy answer is use delete faces on the cavern and it will probably clean it up. but if you need it with a lil flat like the other ribs you will need to do something different.
The link to the file might be important. XD I updated the post, but here's the link as well.

your file appears different than when you asked the question. so not sure if you still need feedback.
I was still trying to figure it out and had it rolled back to halfway through the file. I rolled it to the end though. If you suppress the sketch titled "mohawk" you can see the pictured issue with the top seem.
Found it. Yes you need to set end profile condition to normal in Loft2 and in Loft1 set the 1st two guide profiles continuity to Normal
If you still have issues getting the curvature of Loft to be continuous or having smooth transitions to other surfaces (Shift + C to check curvature of a surface), then you can use Boundary surface which is more controlled than loft. Remember, a surface is only as good as the curves you use to make it. Shift + C will also let you check the curvature of curves and sketch curves.
