Moving my ETH back to Ledger Nano

Excuse me in advance for my extreme ignorance, but with the shitstorm that's going on on so many lending platforms and exchanges, I decided it's time to move my ETH back to my Ledger Nano. My keys, my coins right.

However, when I started my Ledger's application on my PC again, it mentioned how ETH is legacy and how it's now LPT or something.

What the hell is that? Can I safely move my ETH to my Ledger? Will it still be ETH once I moved it or will it be converted to whatever this LPT is?

Can someone ELI5 this to me?
