Cannot declare class PlacemarkVisualization

the next day I don't know how to fix this error
I have two similar solutions where one works
and shows an error on the second page -> Fatal error: Cannot declare class PlacemarkVisualization, because the name is already in use in ...../html/components/com_zhosmmap/views/zhosmmap/tmpl/display_map_data.php on line 4695

I have reviewed and unified the settings according to the working page but still without success
Will you help me

Is it appear in case plugin call?

Do you use last version of component?

I have the same problem with nonumber tabs , 2 tabe and 2 maps load (with plugin zhosmmap) . Blank page. The error is:
mod_fcgid: stderr: PHP Fatal error: Cannot declare class PlacemarkVisualization, because the name is already in use in .../components/com_zhosmmap/views/zhosmmap/tmpl/display_map_data.php on line 4710

I managed to work once adding sometime a placemark but continued adding other placemarks the error continued

yes i call plugin two maps on one page
<div> {zhosmmap: 26 ;;; 200; 400} </div>
........
<div> {zhosmmap: 27 ;;; 200; 400} </div>

joomla 3.9.15
Zh OpenStreetMap 6.3.2.0
Zh OpenStreetMap Plugin 2.1.2.0

Check new version in 5 minutes. I think I fixed it.
