[5.2] Articles Module: problem with category option as link

[Kostelano]

Steps to reproduce the issue

The new module has an option:

MOD_ARTICLES_FIELD_SHOWCATEGORYLINK_LABEL="Category Link"

Category as link is never shown as an option because:

showon="title_only:0[AND]show_category:1[AND]card_link:0"

This card_link:0 needs to be removed or revised.
I didn't find where this is used, but it is also available in the single plugin file with demo data:
plugins\sampledata\blog\src\Extension\Blog.php
