Text Import Wizard

We are having issues with only a certain number of points are being loaded in to the Text Import Wizard, not all points in the survey data-it's only loading 30 points. After looking at several videos and scouring the internet, I've noticed that there is an option for "range", however, I do not have that option.  Have you seen this before? My thought is there may be a Microsoft add-in that is missing and is restricting the full usage of the product. I've tried this on brand new installs of SS10. Any assistance is appreciated.

Thank you,
