That's what I'm thinking, but if the bridge is moved forward it overlaps the pick guard, which is the first time I've seen that problem.
Normally the gap between bridge and pick guard is too big and needs reducing anyway.
This is what I had on the Rellicaster

Does the neck have an overhang? This is a 21 fret, no overhang.
and this is a 22 on my Sonicaster with an overhang, you can just see it above the humbucker.
If you have 22 frets and no overhang, then as you suggested above, perhaps the neck is not the right match for the body. Again, never heard of that, but there are often oddities in these kits.
While the kits are a pretty good start point, it's not uncommon to have to do some rectification of various issues along the way.
