Retention reset but Argument still exists

Hi All

My original post on how to add the retention policy.
I successfully managed to update this retention policy to 1 year and it was working when I first applied it.

But now for some reason is not working any more and has gone back to the default 15 days retention.

I checked the flexlm exporter plugin we use for generating the results to prometheus but it looks like prometheus stores all the data.

What are my options to fix this?
I did read that I could move the data retention file, could that solve it?
