Dell Update Catalog - Categories are ignored in Configuration Manager

Hi There,

I‘have started using the Dell Third-Party Updates in Configuration Manager (2107).
at the beginning, I selected only one model in the “select categories for synchronization” (7210 2-in-1). But after the first sync the console showed me now over 6000 Dell Updates. It seems, that the category selection is being ignored.

I already tried to remove everything:
- unsubscribed the catalog
- deleted the catalog
- removed the selected products in the SUP Component Products List
Then I waited till all the 6000 Updates disappeared from the console (7 Days) and started all over again, with only one model selected: The result is the same, after the sync it shows me again about 6000 Dell Updates in the console.

Am I missing something or is this by design, or does the category selection not work anymore? I have seen videos from 2020, where it seemed to work as expected.

Thanks in advance

Malte
