Lumira Cloud - column as number or string

Hello everybody,

So I was trying to see how the GeoMap feature works in Lumira Cloud.

But I couldn´t make a proper scenario to work. And I think there´s an issue in my dataset or there is a problem in the app itself.

I just made a simple dataset to try it out (attached in this post).

When I create the dataset, I see that Longitude and Latitude are considered as numbers.

But when I select to explore the dataset, Longitude and Latitude are considered as String.

And because the Explore tool sees these columns as strings, I cannot add them in the filter for Longitude/Latitude.

Could someone help me to identify where could be the error?

Thanks and regards,
Rafael
