It’s problematic that you can’t have a decimal point in the point ID, it’s normally used to indicate it’s a line. Most software can interpret it as a line when importing.
A quick fix would be to use semicolon in the csv file instead of decimal point.
We surely want the points to be indicated correctly. However, I haven’t seen any similar issues, so I’ll need some details from you to be sure how it works.
Which decimal point do you mean? Please share a CSV file example so that we can look into it.
