You need to have your gutters reinstalled with coil stock aluminum installed under the drip edge (roof or gutter apron). Coil and gutter should also be laped and screwed thru the gutter into the soffit. Otherwise you will have fascia rot and leaks when water travels between the gutter and house. Drip will be constant and will erode both house and land.
Down and dirty temporary solution (five years or so): caulk the lip of the gutter to the fascia. Keep fascia painted. Rot will be prevented if you maintain.
As a gutter contractor I would say your installation was not "in a workmanlike manner". In Nebraska and Iowa there are grounds for a Better Business Bureau or States Attorney General complaint as a violation of contractor standards.

In most areas, drip edge is not really the preferred gutter flashing material. We install gutter apron, which is L shaped, where you image a drip edge is T shaped. The difference is usually the exposed face of the metal flashing. A gutter apron is usually "taller" than a drip edge. Though any metal flashing can be bent to any profile. The off the shelf gutter apron is usually 2" tall while the off the shelf drip edge is usually 1.5" tall.

The exposed wood may be a symptom of another problem. Why is the wood exposed? Is the gutter too low? Is it a long run of gutter so it drops several inches from one side to the other? The exposed wood may be a sign of a bigger problem.

At minimum your gutter brackets should be removed and a new proper gutter flashing installed. The flashing may need to be custom fabricated from coil stock. This is not unusual to have to fabricate a gutter flashing.

Caspers suggestion of a slip metal behind the drip edge and over the gutter will also work. I would suggest this if your existing drip edge can not be remvoed, for example if the roofers sealed to it with ice shield.

If the gutter is installed too low you will want to gutter to be raised, but it can also be installed too high. There is a happy medium. For example on metal and some tile roofs, the top of the outer edge of the gutter should be 1" below the plane of the roof, if you project that plane past the gutter. This is because metal roofs are so slick, much more slick than a typical granulated asphalt shingle roof, that snow slides very quickly down and can take the gutter with it. In these cases almost always a custom gutter flashing is necessary.

If there is a very heavy pitch to the gutter, let's say 3" from one side to the other, this may simply be too much. The minimum pitch is 1/4" per 10'. So a 40' length of gutter will drop minimum 3/4". Remember this is minimum, in most cases a 40' gutter should drop a couple inches. This also brings me to another rule of thumb, a 40' gutter I would typically recommend 2 down spouts. Having 2 down spouts allows you to crown the center and split the pitch, thus reducing the drop in half.
