SEPM 12.1RU4MP1a keep 30 definitions instead of 10

Hi, today I run out of space on disk E: on my SEPM. I went to "Administrator" -> "Server" -> "Loca site" -> "Liveupdate" tab and set "Number of content veriosn to keep" to 10

Then I delete some folder in :

E:\Program Files\Symantec\Symantec Endpoint Protection Manager\Inetpub\content\{07B590B3-9282-482f-BBAA-6D515D385869}

and

E:\Program Files\Symantec\Symantec Endpoint Protection Manager\Inetpub\content\{535CB6A4-441F-4e8a-A897-804CD859100E}

I restart the SEPM, but it still continue to restore 30 versions of definition !!!

How to tell SEPM to stop to restaure unneed version of definition ?

Thanks.

P.S.: I know that SEPM 12.1RU5 will change the way how SEPM will store definition on the disk, but the French release is not available for now.
