I have two custom field types Single Image and OSM Map on a standard WP Post. These work well on the backend - (1) users can upload an image and (2) set an address for the map to display - respectively,
However, the map does not display on the same post when the Single Image is also shown. When I remove the Single Image display block, then the OSM map starts to display.
Theme used for testing is Twenty Two Theme. I am using MB Views (shortcode method) to display these elements. No other pagebuilders or Gutenberg blocks are involved.
If you need it, I can provide such access for you to verify the scenario.
