Solana - Block.slot and Block.height are messed up

[BeaRRRRR]

my code:

Run:

╰─ node -r dotenv/config lib/main.js solana                                                         ─╯

Then i change Block.from to 299900000

and now my code:

 for (const block of ctx.blocks as Block[]) {
    console.log('Block:', block.header);
}

gives me this:

Block.slot on the screenshot is actually a block height. Look at solscan and compare (by blockHash)

My questions:

1. Why when i set .SetBlockRange({ from: Number }) - it is NOT height, but in the Docs it says its block height
2. in the logs Block.slot is actually a height, NOT a slot.
3. How to setup SQD to index Solana by real block height, not some weird value 299900000 that is not a slot and not a block height?
4. What is Block.height in the logs then?

Solcan displays block slots and doesn't display height

Yeah, it's pretty clear from subsquid docs that we should always use blockHeight and not slots.

It's solscan which is confusing us

e.g; https://solscan.io/block/311495068

Here 311495068 is slot not height
