What you may have to do is create a plane at this angle and manually place this dimension in your drawing. This is what I have to do when some dimensions do not come in correctly from the model. Especially angled ones!!!
I know it's been a while since you asked about this, but I figured I put my two cents in. Starting in SW 2015, at least from my research, there is a display option to manipulate this issue:
there is an option to show the vertically opposite dimension:
And one to show the explementary (either of two angles whose sum is 360°, for those who have to look it up ) angle:
I hope this helps.
