Supplier audit doesn't show anything for when a supplier contact has their phone number amended

Content

Hi,

I've got through the guides and have enabled *every* checkbox (that's not an attribute). However when we make an amendment to a supplier contact, as an example, make a change to their phone number, this is now shown in the audit report

Should it be? If so, why is it not showing for me? If not, how can I see this amendment?

Thanks
