@nchaulet I've reported a similar issue here: [Fleet UI] Advanced Settings for Agent Policy shows duplicated and confusing configuration information · Issue #207960 · elastic/kibana · GitHub
There is another issue that is related to the description of the second setting, the logging rotation interval.
In the example it says it supports 7d, but it only supports interval described as hours.
There is also this related issue: Fleet policy setting "agent.logging.files.interval" misleading setting description · Issue #44525 · elastic/beats · GitHub
