Segment not working also after cron update

Hi, I have this problem with our Matomo On-Premises installation.

Recently I created a segment to “Exclude” some king of visits from my reports.

The segment is based on this rule:

Resolution > Not contain > 800x600

OR

Resolution > Not contain > 1600x1600

Unfortunatly in my “Devices” report this values are both still present inside the Resolution table.

I launched a cron job for updating but still no effect.

Some ideas about?

Here a screenshot:

Thanks in advance!
