The two tests are not testing the same thing.
When you get a not significant (p=0.1055) p-value for the Type 3 test, this means that the slopes (regression coefficients) of the four different levels of EDU4 are not statistically different from each other — i.e. they are all the same.
When one of the estimates for the levels of EDU4 is significant (p=0.0221), this means the slope for this level is significantly different than zero.
These are not testing the same thing. One does not imply the other.
