Pixelmon Wiki says that when catching a Burmy, it will change forms depending on the terrain it is caught on. Grass - Plant cloak, Sand / Clay - Sandy cloak, other - Trash cloak. I noticed this issue on a server I play, and went to test on a singleplayer world to see if it was just a server issue, but the same happens in singleplayer. Caught few Plant cloak Burmys on the server and singleplayer world on grass blocks, and all changed to Trash-cloak Burmys. I have screenshots if needed.
