Are you selecting the elements before you try to use the automatic dimension?
Personally I wouldn't worry about auto dimensions.
They are not perfect and I find that by the time I find and fix the problem dimensions and then move them to insert some internal auto dimensions then I might just as quickly have dimensioned the job manually.
At least that way I get exactly the dimension I want where I want it.
