Missing rows in the dataframe; not showing up on the map

[perfectly-preserved-pie]

Some of the rows aren't getting rendered on the map. Why?

INFO:root:The original dataframe has 1296 rows. There are 1208 rows in the filtered dataframe. There are 1208 markers on the map.

That's ~90 rows missing, even with all options/checked. There shouldn't be any actual filtering going on.
