Plugin breaks custom uploads folder

The following problem:

I defined a custom “uploads” folder for my WordPress installation like this (in the wp-config.php file):

define('UPLOADS', 'my-custom-folder');

Now as soon as I have the Kadence Blocks plugin activated, it breaks my custom uploads folder and uses again the default “wp-content/uploads” folder (for all new uploads as well for all existing uploads – meaning all old uploads produce now a “404 not found”, because the actual files are still in “my-custom-folder”).

I’m not sure with which version exactly the problem was introduced, but reverted back to version 3.1.26, and here it still works. But with the latest versions (tested with 3.2.24 and 3.2.26) I have this essentially site breaking bug.
