Hydrophobic soil or paranoia

Recently build a raised garden bed. Bought a few m3 of vegetable mix soil which was delivered yesterday. The goal was to top the bed and replensish the rest of the garden so can plant my winter stuff.

After watering the bed I noticed it wasn’t draining. Spent the morning mixing water through the soil to get it wet. Went as far down as I could go without hitting twigs and branches and bottom filler stuff but it seems it’s not draining.

Any help. First pic is after sitting there all day in the hot weather today. It’s still mud where I mixed it. So

Any ideas what might be happening, is it hydrophobic Any solutions for the bed? Any suggestions for what to do with the pile of soil I was going to mix into the rest of the garden to prevent the same issue happening everywhere?
