Question about Vivaldi Gloria RV 589 / Handel Concerto Grosso Op.6 No.4 recording

Hello Musopen Team, I would like to ask about the following recording: Antonio Vivaldi – Gloria in D major, RV 589 https://musopen.org/music/3750-gloria-in-d-major-rv-589/ I noticed that this same audio file also appears under: George Frideric Handel – Concerto Grosso No.4 in A minor, Op.6 https://musopen.org/music/5848-12-concerti-grossi-op-6-hwv-319-330/ Could you please clarify: 1. What is the correct performer for this recording? 2. Is this recording truly Public Domain (PDM 1.0)? 3. Is it a mistake that the same audio appears under two different works? Thank you very much for your help.
