First thing is you need to be patient. It takes a lot of practice to get fletching done right. Especially figuring out how much glue to use and adjusting a jig for fletching contact. If the front or back is off you need to find the happy middle ground.You may have to put foil ortape in the V on the front if the front of the vane will not lay right. Skinny arrows sit much deeper and can be a pain.You do have the isntruction, right? If you take your time and follow them you will eventually have great looking arrows.
