Waxing Gibbous: 90-180 degrees my solar lunar arc is 147 degrees

So i would interpret that as me having been born during a waxing gibbous moon.

But when I look at the timeline diagram in the Solar Lunar Return arc section of the Dashboard, the green highlighted area occurs after the full moon — which means my solar lunar return arc is happening during a Waning Gibbous?

I had also noticed this when I tap on the Date & Time of my natal chart. Solar Lunar Arc is 147 degrees, but the moon phase for my birthdate is Waning Gibbous.

I am confused (lol) because I thought the lunation phases are directly related to the angle between the sun and the moon (180 degrees between them = full moon)
