3D Block models have wrong / and white textures

Hi. Can anyone help me with getting 3D Block models imported right into Mcreator and to Minecraft? I'm trying to create them with JSON files created in MrCrayfish's Model Creator and I think I have created them atleast right in the MrCrayfish's program. I only used default textures and I put right textures with right order into boxes I got on screen when I chose JSON file and in game the items I've made appear to be white and mistextured; look at the pic: (Donut pile isn't supposed to be only light brown, they have toppings and such, and the boxes are only white. What goes wrong? And yes, I also tried with only default texture pack but result is kinda same.
