It seems that when importing content from one course to another, if there are images in a tab, these are not imported.
I'm referring to this tab display module: https://docs.moodle.org/36/en/Tab_display_module
The links appear to be broken - it seems that the number (in bold) is different to the number for the same link in the course from which the image is imported. https://moodle.xxxxxxxx.edu/pluginfile.php/5980756/mod_tabbedcontent/tabcontent/4509/asahi.jpg
