When this plugin is enabled...crossbredding does not work.

You can disable automatic pickup and then plant cloning.
Or reduce it.

    "PlantEntity": {
      "Enabled": true,
      "Check Radius": 0.5 ///Or reduce it
    },​

Even with AutoPickup disabled as a player the plants will not cross breed on the server.
I have to unload the mod for plants to cross breed.

Can you record a video?

Uploading now. Link here? Or somewhere else?
