When switching between persons, the Add Provision screens takes the person details of the latest person.
This is a known bug and will be fixed in a future version. In the meantime, the header has been temporarily removed from Mosaic 22.1.0.0.
Steps to replicate
Open a person (PersonA) and start a Finance purchase step.
Leave the step open for the PersonA and in main Mosaic window open another person summary PersonB.
Now go to the step of the PersonA and ‘Add Provision’. Add provision screen shows the person details of PersonB instead of PersonA.
Only the worker who has work with all said named persons will be exposed to these names and therefore there is no risk of workers who shouldn't have access to seeing names as it is down to the session variable that a particular worker has open. So, it's more about workers being aware of the issue.
So where possible, avoid opening a different person record whilst working in a finance step, if the wrong person name is displayed then save and close the step, reopen, and review.
