Product Feature Variant mainbox-title

Does anyone have any idea how I can edit the mainbox-title on individual product feature variant pages? I noticed on all product feature variant pages it just shows the variant and not the actual feature name.



For example: I have a feature called Belt Width. I have various widths, Small, Medium Large.

When I visit the variant page for each width the mainbox-title simply says “Small” so the customer will have no clue what that means. We really need to figure out how to show the feature title Belt Width. Then it can properly say



Belt Width: Small.



Anyone have any idea how I can do this? PLEASE :)
