The values registered in the Title and Alt of the SKUs' secondary images are being replaced by the values of the main image.

1. Edit an SKU;
2. Register more than one image for the SKU with distinct values in the label and text fields;
3. On the product page, note that the values printed in the HTML of the secondary image(s) are the same as the one in the first image.

There is no workaround for this scenario.
