Can anyone tell me why these Pincha's won't get planted?

Title says it all. I've been racking my brain trying to figure this out. I cannot seem to find the solution. I've tried dismantling and rebuilding. I dunno what else to try...

Have you tried save/reload?

They can't reach it from below or above like the other ones. Maybe the diagonal reach doesn't work for farm tiles.

Well deleting the tiles about worked. I don't understand why because they still had to fill it from the corner, but whatever. Seems like some odd mechanic here. Thanks Sakura.

I thought about that, but i ruled it out because the 2 tiles below the liquid lock worked, so i assumed those should work too.

The dupes had to stand on the insulated tiles to reach those. They can't reach through corners from ground level, but can if they're up a level.

You run into the same restrictions when building vacuum food storage that dupes access through a corner.

Ah yes... The "weird reach. I actually forgot about that 

@KnoBuddy the reach of the other two plants below the water lock would probably look like this:
