Map Markers Not showing from SQL on Joomla 6.1

Hello sir. Congratulations on the project and my finding it!
Do you accept USDt. I will donate if I can get things working.

Not normally stupid, I cannot get map markers working.
Joomla is 6.1

Table:SELECT latitude, longitudeFROM joomla_db.c6x9d_geo;

(see first image)
Structure:Latitude=latitude
Longitude=longitude

No other fields changed
 
The map shows but no markers.

Any chance of a step by step for map markers? 

Regards
