whats wrong with my variogram xaxis of ordinary kriging(geostatistical wizard)

Hi,every one. I am working on geostatistics with arc GIS and facing one very basic strange problem.I am doing ordinary kriging through geostatistical wizard of ArcGIS using the data set(excel file) i attached in this post.This is the process i did

1)added data through "add XY data " under file tab . then  changed its coordinate system(the excel file contains lat,lon which refer to GCS).so  I projected it onto UTM coordinate system.
2)Then exported the data to file "export_output".After that using geostatistical wizard i performed the ordinary kriging.I checked variogram for both projected and unprojected.

Data Type: Shapefile Feature Class
Shapefile: C:\Users\IIT\Desktop\arcgis\Export_Output_2.shp
Geometry Type: Point

Projected Coordinate System: NAD_1983_NSRS2007_UTM_Zone_14N
Projection: Transverse_Mercator
False_Easting: 500000.00000000
False_Northing: 0.00000000
Central_Meridian: -99.00000000
Scale_Factor: 0.99960000
Latitude_Of_Origin: 0.00000000
Linear Unit:  Meter

Geographic Coordinate System: GCS_NAD_1983_NSRS2007
Datum:  D_NAD_1983_NSRS2007
Prime Meridian:  Greenwich
Angular Unit:  Degree

and this is the wierd  variogram plot i'm getting

The below is the variogram for  GCS COORDINATE SYSTEM

The main issue is that the variogram plot should be till half the maximum distance.Here the x axis is supposed to be h*10^-5 but it is showing 10^-1.(  This data set has a max distance of 1000 kms. so when projected onto UTM ,the variogram X axis should be h*10^-5.But it isnt.) I dont understand why. please some one suggest me the mistakes or is it my installation problem
