Can you post a twbx with your data? If not, can you share a small subset that demonstrates the problem? Having the working map as well as the broken map will help other folks here take a look at the issue.
Hi Dan, thank you. I updated my original post. Added twbx with few comments. Thank you in advance for any hints.
Interesting, I've never seen this before. It makes me think that Tableau does not like having two different latitudes used in the same map as either the original latitude or the calculated latitude work fine alone. Kent Marten got any ideas?
