Image URL not Imported Correctly

I exported a post (using WP ALL EXPORT) that has 3 custom fields (Advanced Custom Fields), one of which is an image. The exported Image URL field contains both the featured image and custom image separated with “|” and looks like this:

When I import the records back into the post, WP ALL IMPORT or perhaps WP doesn’t load the full contents of the field, only the first image URL. In other words, the separator and second URL are ignored. Even though the URL for the custom image is in a separate field, and that field imports correctly, the image does not appear due to the Image URL field being imported improperly. Please advise how I can configure the WP ALL IMPORT settings so that this field imports correctly.
