You could get some felt and cut it to the width in between the rafters. Slide it down so it covers the gap by at least 4 inches and then you could use some sealant on the right hand side to stop any small drips.
Roofer here and it's terrible.
Bonding gutter isn't straight and the cuts up it are all over the place.
The uplift at the windows is definitely a bit much, they should be able to sit down a good bit more than that.
You can get rafter arms that you can attach the plastic gutter clips to. It would save installing a fascia.

Keyline if it is in your area sells Marley, Osma is available at one merchant I've been to in central Scotland. Flopast is good quality, I use it on most of my jobs
They are handy kits and will weld lower codes of lead to a average standard. A better kit would be one with actual acetylene welding kit. They don't have to be huge because acetylene in it's liquid form can expand by about 600x if I remember correctly
The oxyturbo kits don't use acetylene (they have a ****ty gas). I would invest in a better kit that has the proper gas as the finish on your work will look much better
It's not fitted properly....

Easy trim is cheap crap to be honest with you. The unions are not sturdy in the slightest.
Whoever done this didn't do the job right. They unions need to have a small plastic clip inserted at the top and by the looks of it they never bothered using it.
It will leak eventually.
The black plastic is a type of felt too. None of that should be showing.
I would have a company come and do a report for you because if it's left like that there will be more leaks further down the line.
