What is that dimensioning to?

I don't know about Catia but in SolidWORKS if you dimension to a centerline it can sometimes do that because the feature could be a revolve and it can be dimensioned as a radius or a diameter.

Its in half-Dimension mode.

remove old dimension & then create a new dimension, but before you click the location, right-click and turn off the half-Dimension option,as u turn it off, all new dimensions will be normal.
