Lesson 9: "records players when they enter" doesnt work when all the tests are ran at once, but works when ran individually

[thedreader]

const { assert, expect } = require("chai")
const { getNamedAccounts, deployments, ethers, network } = require("hardhat")
const {developmentChains, networkConfig}= require("../../helper-hardhat-config")

!developmentChains.includes(network.name) ? describe.skip : describe("Raffle unit tests", async function(){
   let raffle, vrfCoordinatorV2Mock, raffleEntranceFee, deployer, interval
   const chainId= network.config.chainId

   beforeEach(async function() {
      deployer= (await getNamedAccounts()).deployer
      await deployments.fixture(["all"]) // deploys all the deploy scripts
      raffle= await ethers.getContract("Raffle", deployer) //signing contract with deployer address
      vrfCoordinatorV2Mock= await ethers.getContract("VRFCoordinatorV2Mock", deployer)
      raffleEntranceFee= await raffle.getEntranceFee()
      interval= await raffle.getInterval()
   })

   describe("constructor", async function() {
      it("Initializes the raffle correctly", async function() {
         const raffleState= await raffle.getRaffleState()
         assert.equal(raffleState.toString(), "0")
         assert.equal(interval.toString(), networkConfig[chainId]["interval"])
      })
   })

   describe("enterRaffle", async function() {
      it("reverts when you dont pay enough!", async function() {
         await expect(raffle.enterRaffle()).to.be.revertedWith("Raffle__NotEnoughETHEntered")
      })

      it("records players when they enter", async function() {
         raffle.enterRaffle({value: raffleEntranceFee})
         assert.equal(await raffle.getPlayer(0), deployer)
      })

      it("emits an event on entry",async function() {
         await expect(raffle.enterRaffle({value: raffleEntranceFee})).to.emit(raffle, "RaffleEnter")
      })

      it("doesnt allow entrance when raffle is calculating", async function() {
         await raffle.enterRaffle({value: raffleEntranceFee})

         //we go though the interval time to activate checkUpkeep and change OPEN to CALCULATING STATE
         await network.provider.send("evm_increaseTime", [interval.toNumber() + 1]) 
         await network.provider.send("evm_mine", [])

         //we pretend to be a chainlink keeper
         await raffle.performUpkeep([])
         await expect(raffle.enterRaffle({value: raffleEntranceFee})).to.be.revertedWith("Raffle__NotOpen")
      })
   })
})

Please, explain to me why player is not getting added to the address array when all the tests are run at once, and then getting added when the test is run individually.

try: ( adding await ) because it's moving to next line without waiting for results
await raffle.enterRaffle({value: raffleEntranceFee})
