Why Change to ATTI after RTH

[stuka75]

Below are excerpts from flight log just after RTH kicked in. Any idea why Mode changes from gps atti to atti, and then back again several times?
thanks

Rather than looking at a confusing Airdata summary, look at actual flight data.
Go to DJI Flight Log Viewer
Follow the instructions to upload your flight record.
Come back and post a link to the report it provides
