When using "NodeLink" for a "Read more" link you can add some CSS classes in the field configuration form in "Link class" input.
In the output the CSS classes are added twice.
Not blocking, juste anoying :)
When checking the code in https://git.drupalcode.org/project/ds/-/blob/8.x-3.x/src/Plugin/DsField/... & https://git.drupalcode.org/project/ds/-/blob/8.x-3.x/src/Plugin/DsField/...
The classes are added both :
arraystring.It use the Drupal twig function link some line before https://git.drupalcode.org/project/ds/-/blob/8.x-3.x/src/Plugin/DsField/...
On a Drupal 10.4.5 https://github.com/drupal/drupal/blob/10.4.5/core/lib/Drupal/Core/Templa...
We can see that it merge the attributes, but the classes dont have the same type.
It result on the list of classes in the array + the string of same classes added in the output.
My easy solution, send an array too! Drupal will only keep one class if added twice or more.
Here https://git.drupalcode.org/project/ds/-/blob/8.x-3.x/src/Plugin/DsField/...
Change
$link_attributes->addClass($config['link class']);
For
$link_attributes->addClass(explode(' ', $config['link class']));
Et voilà :)

Just FYI as they use the same Field extending DSFieldBase all DS fields got the same issue with this Link Class config.
Ha, funny! Could you create a merge request from that, the fix is working indeed!
