I ran into this today, and my best guess is that I was trying to use ASCII columnar data rather than Standard Keyword data.
File that didn’t work:
| MD | TVD | EW | NS | INC | AZM |
| 2018 | 2018 | 0 | 0 | 0.57 | 63.8 |
| 2070 | 2070 | 0.42 | 0.33 | 0.57 | 49.74 |
| 2160 | 2160 | 1.37 | 0.69 | 0.88 | 66.9 |
| 2250 | 2249.98 | 2.9 | 1.4 | 1.19 | 68.68 |
File that did work:
