Also be sure that Include's min and max args are vectors since you are feeding vector data, else it will take the mag(vector) if you send min-max as scalars.
If there are no invalids, do you have any problem with the vectors? You could test this by Compute( a == -9999 ? 0 : a ) to temporarily override your invalids.
Be assured that under normal circumstances, what you propose to do works. The vectors should "emit" from their "positions" (which are treated as local origins for each vector) and extend in their vectorial direction (given by the "data"). The only thing that should change is that the invalidated ones will disappear. If you try the substitution idea, the "invalids" will become spheres at their base positions (but of course, this can't be distinguished from a "valid" [0, 0], so again this is just for testing.)

Thank Chris for your help.
I tried other methods you mentioned but I have same problem unresolved yet, they didn't make any differences.
It is so weird, I spilted the series data into pieces for every time series and subsituted the missing values to a certain values and tested.
but then it is same, just X vaules are shifting.
I am sure but the missing values are doubtful since they are all X values without any missing values in Y.
Alternatively I have same data in netCDF with variables such as elevation, temperature and wind velocity(wu, wv : this is same wind field)
and tried to make 2-vector field with compute module. In this case I don't have any images in ImageWindow, just black, and even any error messages. The modules I used are like below;
--> import (wu)
Sequencer ("import wu, wv separately") --> compute([wu wv]) --> reduce --> include --> autoglyph --> autocolor --> image
--> import (wv)
Thanks in advance.
