Missing some machine learning jobs

Elastic Stack Elasticsearch
1

Hello!

Recently I noticed that some ML jobs that start with "v3..." are missing.
I can find other jobs that start with "v2..." under Machine Learning > Anomaly Detection > Jobs, but not "v3...". Some rules complain that they require this job to run properl, for example: Unusual Linux Username | Elastic Security Solution [8.8] | Elastic.
I am using Elasticsearch 8.8.1, I did recently upgrade from 7.17.x (started using ML somewhere about 7.15).

Reinstalling " Prebuilt Security Detection Rules" integration did not help.
Running the following API request did not help either:
curl -X PUT -u elastic:changeme "http://localhost:5601/api/detection_engine/rules/prepackaged" -H 'kbn-xsrf: true'

What am I missing here?

I was able to solve this by deleting all rules under Stack Management > Rules, then all jobs under Stack Management > Machine Learning.
When there were no rules loaded, a button appeared that allowed me to load prebuilt rules that also contained the v3 jobs.
