Contabo's Object Storage - Object Lock Retention (AWS S3 compatible)

I'm having difficulty with Contabo's Object Storage.

With a user with permission: "S3 Object Storage Read and Write" I configured a aws profile called 'backup'.

With this profile, I ran this shell script:

echo "Bucket: "$BUCKETecho "Key: "$KEYecho "Profile: "$PROFILEecho "Region: "$REGIONecho "Endpoint: "$ENDPOINTaws --profile $PROFILE --region $REGION --endpoint-url $ENDPOINT \   s3api get-object-retention --bucket $BUCKET --key $KEY

And then, I got this result:

Bucket: test1Key: test_one.txtProfile: backupRegion: defaultEndpoint: https://usc1.contabostorage.com{"Retention": {"Mode": "COMPLIANCE","RetainUntilDate": "2023-05-06T17:35:57.568865+00:00"    }}

This means that even the root user could delete this file before: "2023-05-06T17:35:57.568865+00:00" right?

After this, I ran this shell script:

echo "Bucket: "$BUCKETecho "Key: "$KEYecho "Profile: "$PROFILEecho "Region: "$REGIONecho "Endpoint: "$ENDPOINTaws --profile $PROFILE --region $REGION --endpoint-url $ENDPOINT \     s3 rm s3://$BUCKET/$KEY

And then, I got this result:

Bucket: test1Key: test_one.txtProfile: backupRegion: defaultEndpoint: https://usc1.contabostorage.comdelete: s3://test1/test_one.txt

So the file was deleted. The retention mode is "COMPLIANCE" and the file was deleted. Why?
