Why is my own texturepack not working?

I'm currently creating a Minecraft texture pack for the 1.16, but the textures are not accepted, I exported the textures in Gimp and tried to overwrite them, but none of them work. In Minecraft, the textures still look like the original. I created a TP for the 1.14, everything works there. The funny thing about the 1.16 TP is that only the blocks don't show any texture. The pictures or the mobs are in separate folders, and when I texture them, this is also displayed. With the blocks, however, only the textures of the new blocks are displayed, if I texture old blocks that come from previous versions, this is not displayed in the Minecraft world. Does anyone know why that is?

Look whether you have entered the names eg iron_sword.png
it must come after the item / block .png
Take a texture pack with the standard textures and then replace the blocks / items

Otherwise I would have no idea
