Please help Root partition is filling up

Hi All,

I constantly receive this message:

Root partition is filling up - please check. Current usage: 93%

--

System Uptime     : 1 day 4 hours 50 minutes

System Load       : 0.40

System Version     : Sophos UTM 9.007005

Please refer to the manual for detailed instructions.

I check on the firewall and I have 2% of space are being used.

Also another problem:

I see on the firewall that I have 37 updates to do, but when I go to the updates is saying that "all is updated to the latest version"

Thanks and best regards,
