cant get a texture pack

I used to play Minecraft bedrock on the Nintendo switch, and I recently started playing on the computer instead. I used to  have a bunch of texture packs on the switch, and I cant find them on the computer. On my switch, I go to "my packs" in the marketplace and there are all the texture packs that I've had all these years. But when I go on the computer and go to "my packs", only a few of them are there. I did notice that there was a "(p)" next to the packs I didn't have on my computer though. I would like to know what that means, and if I can get those packs on the computer.
