[Support request] Custom image size issue, conflict with DO Spaces Sync

We are using Digital Ocean Spaces to manage the media library with the DO Spaces Sync plugin.

The images display fine when using the default settings of WP Show Posts. But when I try to change the image height or width settings, the images stop displaying. No error message but img src=”” (empty). I am sure this is an issue with the DO Spaces Sync plugin and the way it manages the images.

Do you have any suggestions or workarounds? I understand compatibility with all plugins is tough, so maybe a simple CSS/ JSS workaround would also work. My main goal is to make the images equal height.
