Joker'-- that SCH looks like she's bent in a U-shape and is upside down,.. I think that's the tap root tip poking up, and the cotyledons are half buried but trying to orient up,... the GG looks like some of that membrane between the shell and the cotyl's is dried up and binding the cotyl's together... [emoji3] time for some delicate surgery! For GG, just mist it well, let it sit for a minute or to to moisten that membrane, and use a toothpick to tease them apart; use a second toothpick to lightly brace the seedling stem if you need to,... Now the SCH, I'd use that toothpick to gently flick away at the soil surrounding the seedling, exposing it so you can see WTH is going on down there,... if I'm right about the tap root, it'll free up pretty easily, then reorient it with the taproot down, cover it again and we'll see if it takes downward, and the cotyl's bend back up again,... sometime this process just fails, and the seedling is a misfire-
