Reproximation (you've probably seen it referred to on these boards also as IPR - Interproximal Reduction - or even as slenderising) is, of course, when the orthodontist removes a small amount of enamel from between the teeth to help make a little extra space.
As to whether it is fixable with Invisalign, I would guess so (but I am not a dental professional). I don't know if your orthodontist/the treatment plan is relying on it being corrected as a side-effect of tweaking the shape, and perhaps in particular the width of the arches, or if (as I mentioned above) elastics might be included in treatment at some point, in order to change the relationship between the two arches, by pulling the lower arch back just a little in relationship to the upper.
Good luck - I hope the chat goes well.
