Muse Sounds Flute 1 Eighth Notes sound odd

Muse Sounds flute 1 eighth-notes sound like two notes are being played. The tongue articulation is followed by the effect of air support continuing the sound with enough push to sound like another note is started. Is that normal?

Staccato eighth notes don't do it but they are on the quiet side.

Haven't noticed flute players do that in real life but then I've never lived with one.

Flute 2 is normal. So is the thing that flute 1 does an actual thing or a glitch?
