To preface this question I am a little new to Carlson survey. I am trying to import a .xml surface and when Carlson draws the 3d faces everything looks fine but when the contours come in I am getting big holes and mounds does anyone know why that would be? I viewed the surface and it looks fine in the 3d view.
You have entities with odd elevations, could be tidbits of lines, nodes or even text at elevations.
Easiest fix is to freeze all your topo points and breaklines, then select everything else by crossing and set to zero elevation.
Wherever the extra lines are is were you look, but they might not be self evident and may require detail searching if they happen to be on your point or breakline layers.

I will look for those but this is a design surface and the extra contours are inside the triangles.
Do you have the checkbox for "Interpolate peaks and depressions" set? (or whatever the wording is)
That might do it, but my initial question would be,"Does this happen in all of the drawings with all of the other imported xml files?
If so, check every setting in the surface menu to find the cause.
If not, then you have a corrupt xml file.
A computer will only do what it is told to do. The trick will be to find where the bad commands are and re-set them.
(Side note; I do the contouring myself and do not check any of those "helpful" boxes. They seem to do more harm than good. Want to get some really bogus contours? Check the "simplify the Surface" box. ALL of your critical breaklines will be generally ignored. I know many will disagree and that's fine. I've been drawing contours longer than most of the dissenters have been drawing breath. :o) )

One suggestion I'd have would be to validate the structural aspect of the .xml file. Presuming the .xml file is a LandXML file, you could use the LandXML Validator to see if the file conforms to the LandXML specifications.
Otherwise, if you'd care to send me an example of the .XML file and a copy of your Triangulate & Contour settings file (use the Save Settings option to create a *.TRI file) to lnelsonATcarlsonswDOTcom, I'll be happy to take a look and offer any advice/suggestions.
