Issue: Always Linked the first SubCategory - [Fixed in 4.0.15]

[dodogiraccola]

Hello everybody, a strange thing happens to me after updating a site coming from a Joomla 3.9.10 (...however, following the Arno's instructions) with jdownloads:
if I choose the "Multi-Column Subcategories Layout v3.9" layout and I click on the symbol image of the category, the link builded is always referred of the first category even if I click on other sub -categories.

While if I choose the "Standard Subcategories Layout v3.9" layout, the images link is built well and it shown the correct reference category.

If I use the Title Link all things are correct In both layout.
Details in the attached image...
Could it be a bug or anything else?
Thanks in advance to everyone could clarify me this issue.
Bye from Florence(Italy)
