You are using the old style csv files. I would recommend using the 'new' style' csv format. If you have downloaded the files in post #2 of this thread, then use the csv's in the folder named ExampleFiles. See image below.
Use templates in this folder.
After opening the new files, you'll need to keep only the headings on row 1 and delete ALL other rows. The csv titled Orientation and Inclination is NOT mandatory so you don't have to use it, the other two are mandatory and must be completed. Do not change the TITLES of Field Geological Descriptions or Location Details and keep & honor the 'spaces' in those titles. Also, do not change the HEADINGS inside the files and keep the upper and lower case of the used in those headings. If the headings have spaces, keep them exactly as they are. Changing the name of a heading, adding or deleting spaces, or changing upper and lower cases, will cause an error when you input the data.
Before entering your data, it's a good idea to make 'templates' for Field Geological Descriptions and Location Details so you'll have them on hand for future use. Be aware that the Geotechnical Module is very picky on how you input your data so you should also review the 'sample data' in the sample files before deleting them. After you review, save them to make your templates so you'll be better acquainted with how they must be formatted.
